Abstract

The excitation of a linear quantum oscillator (LQO) upon a collision with a charged particle moving in a rectilinear trajectory is analyzed. The probability and the cross section of the process are calculated beyond the framework of perturbation theory for different charges of the incident particle, including multiply charged ions. The excitation between the LQO stationary states, as well as total excitation from the ground state, are considered. The characteristic features of the process depending on the problem parameters are analyzed.

带电粒子激发量子振荡器

摘要

分析了线性量子振荡器 (LQO) 在与沿直线轨迹运动的带电粒子碰撞时的激发。对于入射粒子的不同电荷，包括多电荷离子，该过程的概率和横截面的计算超出了微扰理论的框架。考虑了 LQO 稳态之间的激发以及来自基态的总激发。分析了取决于问题参数的过程特征。
