非共面索末菲参量对三重微分截面的影响

Influence of Sommerfeld parameters on triple differential cross section in non-coplanar geometry

考虑末通道He+中剩余电子的屏蔽效应之后,在非共面几何条件下利用3种不同的修正方案,详细地比较并研究了不同索末菲参量在非共面双对称几何条件下对He原子(e,2e)反应中三重微分截面所产生的影响.讨论了产生这种影响的物理本质.

The effective shield of residual electron in the final state of He＋ is further modified for（e,2e） processes on Helium.Three different amendments to the program are proposed in non-coplanar geometry.The effects of the Sommerfeld parameters on the triple differential cross section and the physical nature of these effects are considered.
