| Abstract: | Considering that the screeing effect of initial channel,the process of the H（e,2e） reaction of low energy electron impact was studied.The triple differential cross sections of the collision reaction of incident electron at 27.2 eV were calculated under the coplanar as mmetrc geometry.Further,the calculation results were compared with the results of 3C,DC3C and CDS3C models and experimental data.The result showed that the above collision process was successfully described,and the coincidence degree with experimental data was improved by CDS3C model. |
