摘要
利用修正的ＢＢＫ理论，考虑入射道的库仑相互作用及出射道电子的交换对称性，在共面－等能分享－垂直角度碰撞几何中，计算了能量分别为８５．６、１０５．６、２２７．６和３７５．６ｅＶ的入射电子碰撞Ｌｉ＋（ｌｓ）电离的三重微分截面．讨论了干涉效应。
Based on revised BBK theory, triple differential cross
sections (TDCS) have been calculated for ionization of Li + (ls) by electron impact. A
coplaner, equal energy, fixed re1ative angle kinematics are chosen and the particular
case where the scattered and ionized electrons emerge perpendicular to each other is
emphasized. The incoming electron state is considered by a Coulomb wave from the
long range attraction between the incident e1ectron and the screened ionic nucleus or
approximated by a plane wave.The electron exchang effect between the two continum
electrons has been taken into account properly.Correlation and coherence between
electron ionized electron, electron proton and electron bound electron are identified and
the influences on TDCS are discussed.
