电子冲击下类氢离子ls→np激发散射的微分截面

The Differential Cross Sections for 1s→np Excitation of Hydrogenic Ions by Electron Impact

用已导出的电子与高离化态类氢离子ls→ns、np跃迁振幅在Coulomb-Born近似下的非分波公式,计算了电子冲击能量分别为1.1、2和5倍阈能,核电荷Z分别为2、6和50的类氢离子1s→2p、3p激发微分截面,详细地研究了强库仑场下各能区截面的角分布特征。

The differential cross sections for Is-2p. 3p excitation of hydrogenic ions by electron impact in Coulomb-Born approximation are calculated using the formula which was derived by us. Results for different hydrogenic ions with Z=2,6, and 50 at different incident energies with X=1. 1, 2, and 5 in threshold units are obtained and discussed in detail.
