Abstract

A three-body classical trajectory Monte Carlo method is used to calculate the nl state-selective charge exchange cross sections in \(\hbox {Be}^{\mathrm {4+}}+\) H(2lm) collisions in the energy range between 10 and 200 keV/amu. We present partial cross sections for charge exchange into \(\hbox {Be}^{\mathrm {3+}}\)(nl) \((\textit{nl} = 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f)\) states as a function of impact energy. Our results are compared with the previous classical and quantum-mechanical results. We show that the classical treatment can able to describe reasonably well the charge exchange cross sections.

摘要

使用三体经典轨迹蒙特卡洛方法来计算碰撞中\（\ hbox {Be} ^ {\ mathrm {4 +}} + \） H（2 lm）碰撞中的nl个状态选择电荷交换截面。能量范围在10和200 keV / amu之间。我们给出了电荷交换到\（\ hbox {Be} ^ {\ mathrm {3 +}} \）（nl）\（（\ textit {nl} = 2s，2p，3s，3p，3d，4s ，4p，4d，4f）\）状态作为冲击能量的函数。我们的结果与以前的经典和量子力学结果进行了比较。我们证明了经典处理能够很好地描述电荷交换截面。
