A propos de cet article

FIRST EDITION of Feynman's proof of the validity of his 1949 "reformation of quantum mechanics itself," work that would "elegantly rewrite quantum theory" (American National Biography; Peacock, The Quantum Revolution, 102). ALSO included is Erwin Hahn's "Spin Echoes," the first detection and report of spin echoes in nuclear magnetic resonance (NMR). FEYNMAN PAPER: In this, the third paper in his pivotal reformulation of quantum mechanics, Feynman provides the mathematical "proof of the validity of the [his] rules for calculations of amplitudes in quantum electrodynamics. Feynman's paper rigorously proved that his treatment of "the problem of molecular forces from a thoroughly quantum-mechanical point of view" was accurate (DSB). Feynman had arrived "at a simple means of calculating the energy of a molecular system that continues to guide quantum chemists" (ibid). In 1965 Feynman was awarded the Nobel Prize along with Schwinger and Tomonaga "for their fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles" (Particle Physics, One Hundred Years of Discoveries, 113). HAHN PAPER: Erwin Hahn's "Spin Echoes," relays the first detection and report of spin echoes in nuclear magnetic resonance (NMR)."In magnetic resonance, a spin echo is the refocusing of spin magnetization by a pulse of resonant electromagnetic radiation. Modern NMR and magnetic resonance imaging make use of this effect. Echo phenomena are important features of coherent spectroscopy which have been used in fields other than magnetic resonance including laser spectroscopy and neutron scattering" (Wikipedia). In 1950, Hahn, then a graduate student, was experimenting with NMR using pulsed RF energy and observed echo signals, hereafter called 'Spin Echo' or 'Hahn Echo' signals. We also separately offer this paper in its original wrappers. CONDITION & DETAILS: Lancaster: American Physical Society, Volume 80, October to December 1950. Bound in green buckram. NOT EX-LIBRARY. Tightly and solidly bound. Bright and clean inside and out. Near fine condition.
