SS. (157)-168. Mit 3 Tafeln. Rückenbroschur. (Aus: Annual Report of the Board of Regents of the Smithsonian Instit.). Wiederabdruck der im gleichen Jahr im "Philosophical Magazine" erschienenen ersten Ausgabe. - Thomson gelingt 1897 die Aufklärung des Rätsels um die Natur der Kathodenstrahlen. Er kann nachweisen, dass die Kathod…enstrahlen aus negativ geladenen Teilchen bestehen, deren Masse 1800mal kleiner ist als die des Wasserstoffatoms. Er wird damit zum Entdecker des Elektrons, das er aber bis 1907 als "Korpuskel" bezeichnet. "Damit hatte er die Physik revolutioniert. Es gab kein 'unzerstörbares' Atom mehr und es fing an, wahrscheinlich zu werden, daß der allgemeine Baustoff aller Materie eine Form von Energie war. Thomsons Entdeckung stellte fast jedem Zweig der Physik neue Aufgaben und öffnete neue Forschungsgebiete" (PMM). - Gut erhalten. - DSB 13, 371; vgl. PMM 386 (a).

Soft cover. Etat : Very Good. Thomson, George Paget. "The Diffraction of Cathode Rays by Thin Films of Platinum." in Nature, Vol. 120, No. 3031, December 3, 1927, p. 802 ("Letters to the Editor") in the issue of pp 793-828. Offered in the original wrappers. VG, solid copy. ".idea of a wave theory of the electron based on de Brog…lie's theory was discussed, and Thomson, already deeply interested in de Broglie's work himself, saw how his work with positive rays might be adapted to test the idea. Reasoning that the effect should be easier to analyze with a solid than with a gaseous target, and that some of the positive ray apparatus at Aberdeen could be readily adapted for such an experiment, he asked Alexander Reid to look at the scattering of electrons through thin celluloid films (3.10−6 cms) onto photographic plates. The result was clear pictures of "halos" much as one would expect from a diffraction effect, and in a joint paper with Reid, published in May 1927, Thomson wrote of celluloid as a "diffracting system" and of the electrons as having "wavelengths" given by de Broglie's theory. Since the structure of celluloid was unknown, the experiment was not conclusive. So Thomson next turned to metallic films of the same thickness, for which the crystal structure was known, and repeated the experiment for scattering from aluminum, gold, and platinum. He found that the dimensions of the observed diffraction patterns agreed in all cases, to within 5 percent, with those predicted by de Broglie's wave theory of matter. These results were published in brief in December 1927 [the paper offered here] and in detail two months later." [++] Sir George Paget Thomson was awarded the Nobel Prize in Physics in 1937 with Clinton Davisson, "for their experimental discovery of the diffraction of electrons by crystals." This December paper is certainly part of Thomson's Nobel Prize effort. [And btw J.J. And George Paget Thomson are one of two pairs of father/son Nobelists along with William and Lawrence Bragg; the only mother/daughter pair was Marie and Irene Joliot-Curie.].

First Edition. Full Description: THOMSON, Sir Joseph John. Cathode Rays. [In]: The London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science. Being a Continuation of Tilloch's 'Philosophical Magazine,' Nicholson's 'Journal,' and Thomson's 'Annals of Philosophy.' Conducted by Lord Kelvin, LL.D. F.R.S. &c. George… Francis Fitzgerald, M.A. Sc.D. F.R.S. and William Francis, Ph.D. F.L.S. F.R.A.S. F.C.S. 'Fifth Series.No 269- October 1897. With one plate. Illustrative of Prof. D.B. Brace's paper on Oberservations on Light Propagated in a Dielectric Normal to the lines of Force. London: Taylor and Francis, October, 1897. First edition. Octavo (8 7/16 x 5 9/16 inches; 215 x 142 mm). 293-368 pp. Thomson's article on Cathode rays comprised pages 293-316 with six black and white line-drawings, some numerical charts and equations. Along this article are eight other articles and one engraved plate. Publisher's original blue printed wrappers, neatly rebacked to style. Edges speckled red. We could find no other copy in the original wrappers at auction. An about fine copy. This was the first of Thomson's papers on the discovery of sub-atomic particles. "It was reserved for J.J. Thomson (knighted in 1908) to discover the true nature of the cathode rays. In April 1897 he gave a public demonstration at one of the Friday evening discourses at the Royal Institute in which he declared that cathode rays are composed of particles of sub-atomic proportions. At this stage, he had been unable to calculate the weight of the particles, but he had measured their rate of charge to mass. The ratio was large, so they must either have a big charge or a small mass. Thomson gave reasons for preferring the latter-from experiments performed by Kenard in particular. If the charge could be calculated, then the mass could be found, since the ratio between the two was known, Thomson eventually succeeded in calculating the charge, by an ingenious adaptation of the 'dust counter' devised by C.T.R. Wilson. Thomson substituted for the dust particles counted by Wilson the cathode-ray particles. By observing variations in their fall in various electric fields he was able to calculate the electric charge of the particles. These experiments, later perfected by Millikan, led to the calculation of the mass of the electron as one eighteen-hundredth of a hydrogen atom, hitherto the lightest known object. Moreover the mass of these 'corpuscles', as Thomson called them, was constant, whatever their origin. That is to say that all forms of matter, no matter how varied their chemical composition, produced cathode rays of uniform make-up. Although he still preferred as late as 1907 'corpuscle' to 'electron' to describe this ultimate particle, Thomson has provided experimental proof of the theoretical speculation of Lorentz. In doing so he had revolutionized the science of physics. The 'indestructible' atom was no more and it began to seem likely that the common constituent of all matter was a form of energy. Thomson's discovery opened up new fields of investigation in almost every branch of physics." (PMM 386). Printing and the Mind of Man 386. HBS 68815. $4,500.

Soft cover. Etat : Very Good. 1st Edition. First edition, complete journal issue in original printed wrappers, of Thomson and Reid's experimental confirmation of de Broglie's wave-particle duality, carried out independently of similar experiments by Davisson and Germer at Bell labs in New York. Davisson and Thomson shared the No…bel Prize for Physics in 1937, for the "experimental discovery of the diffraction of electrons by crystals." Born in 1892, the son of the physicist Sir J. J. Thomson, G. P. Thomson studied at Trinity College, Cambridge. Following a post at Cambridge, G. P. became Professor of Natural Philosophy at the University of Aberdeen in 1922 and remained there until 1930. It was at Aberdeen that G. P. began to carry out experiments revealing the phenomena of electron diffraction, assisted by one of his students, Alexander Reid. In this paper, Reid and Thomson describe the rings formed when a beam of cathode rays was sent at normal incidence through a thin film of celluloid and struck a photograph plate placed some distance behind the film. These were attributed to a diffraction of the cathode rays by the film, the cathode rays behaving as waves of wave-length h/mv according to de Broglie's theory of wave mechanics, and regularities in the structure of the film, or in the size of the molecules, making it behave as a kind of diffraction grating (Abstract). "Thomson arrived at his discovery in Aberdeen at about the same time as Davisson in New York. They announced their discoveries simultaneously in the same volume 119 of the journal Nature. However, the experimental approach and the manner in which the diffraction was observed were completely different in the two camps. Davisson's discovery was accidental, whereas Thomson, inspired by the theory of de Broglie, set out from the start to prove the wave nature of the electron . . . Quite opposite to the approach used by Davisson and Germer, who measured a beam of low energy electrons (54 eV) as these deflected off the atomic plane of the crystal surface, Thomson and Reid used a beam of relatively high-energy electrons (20,000 to 60,000 eV), which would pass directly through the crystalline lattice of thin metal foils . . . Thomson thus demonstrated the de Broglie matter wave. The materials tested by Thomson were polycrystalline meaning that the substance is built up of many crystals having different orientations, such as a powdered sample of single crystal grains. The effect of X-ray or electron diffraction of polycrystalline materials is the production of a diffraction pattern consisting of several concentric rings of various diameters about the central spot produced by the electron beam" (L'Annunziata, Radioactivity: Introduction and History, From the Quantum to Quarks, pp. 431-2). 8vo, pp. cxciii-cxcvi, 881-912, cxcvii-cc. Complete journal issue in original printed wrappers (a little soiled, corners a little worn, library ink stamp in upper margin of front wrapper).

1st Edition. FIRST EDITION IN ORIGINAL WRAPS OF THOMSON & REID'S NOBEL PRIZE WINNING PAPERS "for the experimental discovery of the diffraction of electrons by crystals" (Nobel Prize Portal). The experiments conducted here "beautifully confirmed the [de Broglie's] wave theory" (Lindau Nobel Laureate Portal). Sir George Paget Thom…son was born in 1892, the son of the physicist Sir J. J. Thomson. Paget Thomson studied at Cambridge's Trinity College, later working for a year studying atomic structure with his father; this was followed by work at Cavendish Laboratory until WWI. Following a post at Cambridge, Paget Thomson became Professor of Natural Philosophy at the University of Aberdeen. It is at Aberdeen that Paget Thomson began to carry out experiments revealing the phenomena of electron diffraction with thin metal foils and high-voltage electrons. In 1924, the de Broglie hypothesis argued that a wave must be associated with the motion of any material corpuscle. "Reasoning that the effect would be easier to analyze with a solid than with a gaseous target, Thomson asked one of his students, Alexander Reid, to modify an existing apparatus and investigate the scattering of a beam of electrons with energy in the keV range through this celluloid films at normal incidence" (Lindau). In the first paper offered here (June 1927), Reid and Paget Thomson describe "the rings formed when a beam of cathode rays was sent at normal incidence through a thin film of celluloid and struck a photograph plate placed some distance behind the film. These were attributed to a diffraction of the cathode rays by the film, the cathode rays behaving as waves of wave-length h/mv according to de Broglie's theory of wave mechanics, and regularities in the structure of the film, or in the size of the molecules, making it behave as a kind of diffraction grating" (Abstract). In the paper of 1927 December, Paget Thomson (working alone) confirmed and extended his experimentation "to films of gold, aluminium, and of an unknown (probably organic) substance. In particular, the relation that the size of the rings is in all cases inversely as the momentum of the cathode rays is fully confirmed, and the number and size of the rings correspond remarkably with what is to be expected from the known crystalline structure of gold and aluminium, using de Broglie's expression for the wave- length of the cathode rays" (Abstract). "Whereas his father had seen the electron as a particle (and won his Nobel Prize in the process), Paget Thomson demonstrated that it could be diffracted like a wave, a discovery proving the principle of wave-particle duality which had first been posited by de Broglie in the 1920s as what is often dubbed the de Broglie hypothesis" (Strickland, Creators of Quantum Physics, 180).

1st Edition. FIRST EDITIONS OF FOUR VERY IMPORTANT PHYSICS PAPERS, TWO OF WHICH CONFIRMED DE BROGLIE'S HYPOTHESIS ON THE WAVE NATURE OF MATTER. Davisson and Thomson shared the 1937 Nobel Prize in Physics "for the experimental discovery of the diffraction of electrons by crystals" (Nobel Prize Portal). (1) DAVISSON & GERMER'S 192…7 confirmation of de Broglie's hypothesis --the first observation of the wave nature of electrons. de Broglie's wave-particle duality hypothesis and this 1927 confirmation were major steps forward in the experimental confirmation of quantum mechanics. Though Davisson's discovery was somewhat "accidental", it is considered the "definitive confirmation of de Broglie's hypothesis" (L'Annunziata, Radioactivity, 428; Brush, Making 20th Century Science, 224). (2) THOMSON & REID's purposefully set out to prove de Broglie's hypothesis, the wave nature of the electron. Together they designed an instrument to observe diffraction effects, specifically using transmission geometry with high-energy electrons (Davisson and Germer had used reflection diffraction geometry with low-energy electrons. (3) ELLIS & WOOSTER here demonstrate that beta decay does not conserve energy (they did not know of the existence of the neutrino at the time). "By measuring the average energy of disintegration of electrons in the beta decay of radium E", Ellis and Wooster "firmly established that the energy spectrum of electrons emitted in beta decay was continuous" (Hon, Going Amiss in Experimental Research, 227). (4) MAX BORN'S first description in English of his revolutionary new probabilistic interpretation of quantum mechanics. In 1926, Born published, in German, a series of papers entitled "Zur Quantenmechanik der Stoßvorgänge". The papers presented, explained, and developed Born's probability interpretation (also known as the statistical interpretation) for the first time. In this paper, Born explains that work in English for the first time with the additional goal of making "an attempt to understand the physical significance of the quantum theoretical formulae" as a whole (Born, Nature 119, 1927). ALSO INCLUDED: a hundred page "Supplement to Nature: The Bicentenary of Newton's Death" bound in. NOTE THAT WE SEPARATELY OFFER THE 1927 THOMSON & REID PAPER AND THE 1928 THOMSON PAPER ON THE SAME SUBJECT IN ORIGINAL WRAPS. WE ALSO OFFER DE BROGLIE'S SEMINAL PAPER IN BOTH ORIGINAL WRAPS AND BOUND. CONDITION & DETAILS: London: Macmillan. Complete volume. 4to. 10.5 x 8 inches (262 x 200mm). [lix], 948, [100], 4.
