高分波碰撞强度的研究

A STUDY OF HIGH PARTIAL WAVE COLLISION STRENGTH

本文通过研究Ne-Like Ge^(22+)与电子碰撞激发的一些重要跃迁过程,对分波展开方法中的高分波作三种近似处理:平面波近似,库仑Bethe近似以及下降等比级数近似。并且对这些近似进行了比较。从而解决分波收敛性的问题。

The problem of the slow convergence has been resolved in partial wave expansion for the excitations of electron-ion collisions, with three approximations including plane wave, coulomb Bethe and equimultiple decrease series. As an example, we have computed some important transitions of Ne-like Ge ion and made comparisons between the results obtained by three approximations. The results slow-that all the three methods are acceptable.
