| 摘 要： | 用多通道量子数亏损理论，从精确的类被离子能谱数据推算出低能电子与类锂离子Ａｌ１０＋和Ｓｉ１１＋的２ｓ－２ｐ碰撞激发截面和碰撞激发速率，并与用Ｍｅｗｅ的内插公式计算得到的结果进行了比较，计算结果表明两者差别在百分之五以内。比较可靠的低能电子与类锂离于碰撞激发截面数据对于复合泵浦类锂离子软ｘ射线激光和受控聚变研究具有重要作用。

| Abstract: | in this paper the Multichannel Quantum Deffect Theory (MQDT) has beenapplied to the calculation of the 2s-2p electron impact excitation cross sections and ratecoefficients of Lithium like ions Al10 ,Si11 through the available spectral data of theBeryllium-like ions.The results are compared with Mewe'S values which are obtained byusing interpolation formulae for the electron impact excitation of the Lithium-like ions. It isfound that our calculated values agree within 5% with the Mewe's interpolation results. |
