介绍了对于Na+离子和Rb(5s, 5p)原子碰撞中态选择单电子俘获微分截面的理论计算, 并与实验数据进行比较, 实验结果是离子与在磁光学阱中用激光冷却的碱金属靶原子碰撞而测量到的; 还对高能量质子引起的He原子的转移电离进行了理论研究,在Shakeoff模型的基础上, 分析解释了转移电离截面与单电子俘获截面的比值, 并与最新实验结果作了比较.
We report a theoretical study of state-selective differential single-electron capture cross sections between Na+ and Rb(5s, 5p) atoms. The experimental data have been obtained with laser cooled target in a magnetic optical trap. We also report a theoretical study of transfer ionization of He by protons at high collision energies and analyze the transfer ionization cross section with respect to single electron capture cross section in terms of a shakeoff model.
