Paperback. Etat : New. Print on Demand. This book defines the method to calculate the scattering of electrons from hydrogen atoms with a high degree of precision. In the scattering process, it applies perturbation theory to the full Schrà dinger equation, where the electron-electron interaction alone acts as the perturbation. The results are compared with the original first-order perturbation calculations for this problem. The book differs from previous studies by analyzing the exchange scattering amplitude to high energies of the incoming electron, where it demonstrates that the energy dependence calculated via the perturbation method is different from that obtained using the conventional first-order perturbation method. The author explores the implications of these results and offers reasons for preferring the method used in this book.

Paperback. Etat : New. Print on Demand. This book provides a systematic method for solving the Thomas-Fermi model of the atom. The Thomas-Fermi model is a well-known approximation method used in quantum mechanics to describe the electronic structure of atoms. It is based on the assumption that the electrons in an atom move independently of each other in a self-consistent field. This book derives the Thomas-Fermi model from the many-body description of the atom, which takes into account the interactions between the electrons. The author shows that the Thomas-Fermi model is a good approximation for atoms with a large number of electrons. The book also discusses the quantum corrections to the Thomas-Fermi model, which are necessary to account for the effects of electron correlation.

Paperback. Etat : New. Print on Demand. This groundbreaking book explores the use of interelectron coordinates in constructing atomic wave functions. It presents a novel approach that yields surprisingly accurate values for the energy of various atomic systems, even in zero order. The method involves splitting the Hamiltonian into an unperturbed part containing the interelectron and electron-nucleus potentials, and a perturbing term that is always finite and vanishes when an electron is far from the nucleus. The resulting unperturbed wave function is a product of individual nuclear and interelectron wave functions, while the zero-order energy is the sum of the individual nuclear and interelectron energies. The author imposes suitable boundary conditions on the radial and interelectron parts of the wave function to account for various phenomena, including the physical behavior expected of the system and the shielding of the nuclear charge by the remaining electrons. The zero-order solutions are obtained under these boundary conditions, and the corresponding zero-order energies are immediately found. Applications of the method to various charged, neutral, and excited atoms illustrate its effectiveness, with results that are considerably better than those obtained using traditional methods. The simplicity of the method, coupled with its remarkable accuracy, underscores the significance of the insights it provides into the complex world of atomic structure.

Paperback. Etat : New. Print on Demand. This book examines the scattering of low-energy electrons by hydrogen atoms, a fundamental process in ionospheric and astrophysical phenomena. The author extends variational methods previously developed to handle three-body collisions, calculating the cross section at small but finite electron energies. This work is significant as no data exists for this energy range, and the improved values for the cross section can be used to calculate the resistivity of semiconductors at low temperatures. The book also provides an estimate of the accuracy of the calculation, and discusses the sensitivity of the cross section to the parameters which appear in the effective range theory.

Paperback. Etat : New. Print on Demand. This book explores the fascinating field of electron scattering by hydrogen atoms. Using perturbation techniques, the author delves into the fundamental equations governing these interactions, in particular the equations of motion for electrons in the presence of both the bound electron and the proton in the hydrogen atom. By examining how the incident electron's energy affects the scattering process, the author reveals crucial insights into the nature and evolution of these subatomic reactions. The book is a valuable resource for researchers and students in atomic and particle physics, providing a comprehensive understanding of electron-hydrogen atom interactions and their significance in understanding the behavior of matter at the atomic level.

Paperback. Etat : New. Print on Demand. This book presents a new approach to describing atomic systems by introducing interelectron coordinates explicitly. The simplest atomic systems are treated, and excellent results are found in calculating the energy values of the corresponding ground states. In addition, an approximation technique of high accuracy has been developed to handle, mathematically, wave functions containing interelectron coordinates. The new wave function proposed in this book describes the nuclear coordinates as particles filling the bound energy levels in pairs, while the interelectron coordinates are described as particles all piling into the lowest energy continuum state. This significantly improves upon existing methods, and demonstrates how interelectron effects can be taken into account to a very significant extent.
