| 摘 要： | 本文在原有的半经典交换势（ＳＣＥ）基础上，考虑高阶修正后给出新的半经典交换势，并利用这种新的交换势计算了ｅ－Ｈｅ弹性散射，发现在低能区的相移和微分截面都有明显改进，并与实验和其它理论值符合较好．

| Abstract: | In this paper,A new semiclassical exchange potential is obtained byconsidering higher-order terms of the existinsent semiclassical exchange(SCE)potennntial.Calculations were performed for elastic scattering of electrons from helium bby use of the new exchange potential.We discovered that phaseshifts and differentntial cross sections are improved obviously in low energy region and agree well withthe results of experiments and other theoretical calculations. |
