中高能H^+和类氦离子及He原子碰撞中电子俘获截面的计算

Electron Capture by H + from Helium-like Ions and Helium Atom at Intermediate-high Energy Range

用两态原子轨道展开方法研究计算了中高能Ｈ＋与类氦离子（Ｂｅ２＋，Ｂ３＋，Ｃ４＋，Ｎ５＋，Ｏ６＋）和Ｈｅ原子碰撞的电子俘获截面．结果表明在中高能区本文结果与实验较好地符合．

We calculate the total electroncapture cross sections for systems:H ++Be 2+ , B 3+ ,C 4+ ,N 5+ ,O 6+ , and H ++He(1s 2) by twostate atomic orbit expansion method. Our results are in good agreement with the experimental values at the intermediatehigh energy range.
