电子被氨分子散射总截面的计算

Total Cross Section for Electron Scattering by Ammonia

本文利用光学势方法计算了能量在１０－１０００ｅＶ范围内电子被氢原子和氮原子散射的总截面，并利用可加性规则得到了电子被氨分子散射的总截面．计算结果与实验进行了比较，在２００—１０００ｅＶ能量范围内计算结果和实验结果符合得比较好．

A model complex optical potential is employed to Calculate e--H and e--N total cross sections. The total cross settering for electron scattering by the corresponding molecule--NH3(amoina)are firstl obtained by use of the additivity rule over an incident energy range of 10--1000e V.The results are compared with experimental data and other calculation,an good agreement is obtained in intermediate and high-energy region.
