Description

The set of problems of scattering a fast atom on one or two Coulomb centers are solved using the finite difference method to the time-dependent Schroedinger equation. Ionization, charge exchange, elastic and inelastic scattering, as well as tunneling processes are calculated. The ground state contribution into the problem of the molecular hydrogen ion evolution is noted

Abstract (Russian)

Путем применения разностных методов к нестационарному уравнению Шредингера решиется ряд задач квантовой теории рассеяния быстрого атома на одном и двух кулоновских центрах. Рассчитаны процессы ионизации, перезарядки, упругого и неупругого рассеяния, процесс тунелирования атомного электрона в поле иона. Выделен вклад основного состояния в задаче эволюции молекулярного иона водорода
