Ca原子4s2-4s4p电子碰撞激发特性
Theoretical study on electron impact excitation of calcium
摘要
Abstract
The electron impact excitation (EIE) cross sections of Ca atom from the ground state 3p64s21S0 to all of excited states 3p64s4p 3P0,1,21P1 are calculated systematically by using the fully relativistic distorted -wave program REIE06. The EIE cross sections due to different energies of incident electron are studied, and some im-portant conclusions are summarized. Because the electron correlation effects and Breit interaction are considered in detail, the present calculated results show the smaller relative errors with the experimental values in compari-son with the existing theoretical results.关键词
