| Abstract: | Triple differential cross sections of He(e,2e) reaction have been calculated byconsidering screening effect in coplanar asymmetric geometry.These calculations are compared with those given by BBK model,DS3C model,the existing CCC results and the available experimental data.It is shown that the present results,which consider screening effect of the initial channel,are in better agreement with experimental data than BBK model and DS3C model. |
| Keywords: | (e 2e) reaction effective charge triple differential cross section |
