摘要

摘要在中等能量下，用三电子原子轨道紧密耦合方法处理了 He${^+}$-He 碰撞。给出了单电子俘获、靶激发、射弹激发和靶电离的截面。结果总体上与实验数据和之前的理论结果非常吻合。还讨论了 20 keV/u 左右靶激发到 $2{^1}S$ 和 $2{^1}P$ 的最小截面。

Cross sections in ${\textrm{He}^+}+\textrm{He}$ collision at intermediate energies

The He${^+}$–He collisions are treated with a three-electron atomic-orbital close-coupling method at intermediate energies. The cross sections are shown for single-electron capture, target excitation, projectile excitation, and target ionization. The results are overall in good agreement with experimental data and previous theoretical results. The minima in the cross sections for target excitation to $2{^1}S$ and $2{^1}P$ around 20 keV/u are also discussed.
