| 摘 要： | 将光学势方法与可加性规则（ａｄｄｉｔｉｖｉｔｙｒｕｌｅ）相结合，我们计算了能量在１０－１０００ｅＶ范围内正电子被分子（Ｈ２，Ｎ２，ＨＣｌ，ＮＨ３，ＣＨ４，ＳＦ６）散射的总截面，计算结果与已有的实验结果进行了比较。

| Abstract: | The additivity rule and complex optical potential approach have been employed to obtain the total(elastic inelastic) cross sections for positron scattering by a number of molecules (H 2, N 2,HCl, NH 3, CH 4 and SF 6) over an incident energy range of 10-1000eV. The results have been compared with available experimental data, a good agreement has been obtained in higher energy region. |
