Paperback. Condizione: 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. Condizione: 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.
