摘要: 2态强耦合(2cc)和5态强耦合近似方法被用于计算Al10+离子的2s-2p,2s-3p和2s-3s跃迁的电子碰撞激发截面,分析了间接耦合的作用。与扭曲波近似结果比较可以看出,对于共振型2s-2p跃迁耦合效应不是很重要,但对2s-3s和2s-3p跃迁耦合效应是相当重要的。

Abstract: Cross section for the excitation of Al10+ ion by electron impact from ground state to 2p,3s and 3p states has been investigated with 2-state does-coupling (2cc) and 5-state close -coupling(5cc) approximations. The indirect coupling effect has been analyzed, comparing with the results of distorted wave approximation, it is found that the coupling effect is less important for 2s-2p transition, but for 2s-3s and 2s-3p transition it should be taken into account.

Key words: close-coupling, excitation, cross section
