Khara and Moiseiwitsch's polarization potential have been popularized to many electrons target atom scattering, and by using of the effective potential model, we have been calculated the total cross sections and momentum transfer cross sections of elastic scattering of low-energy positron by neon and argon. Our reults are in good agreement with other theoretical results and experiment datum.

The formulae for calculation of slow electron-atom elastic scattering cross sections containing the relativistic effects have been derived. By treating rel-ativistic effects as a relativistic correction potential to the nonrelativistic potential of the target, the effective potential model (Gou et al. 1981) has been extended to the slow electron-mercury collision. The influences of relativistic effects in the collision have been studied.

本文从中心力场下的狄拉克方程出发,推导了考虑相对论效应后慢电子与原子弹性碰撞的截面计算公式,通过将相对论效应以引入相对论修正势的形式计入到入射电子与靶原子相互作用势中,把等效势模型(Gou et al.1981)推广运用到了慢电子与重原子Hg的弹性碰撞截面计算,并着重研究了相对论效应在此碰撞过程中的作用。 采用非相对论Slater波函数描述靶原子,除了考虑库仑相互作用和相对论效应,同时还要考虑交换作用和极化作用,本文计算了入射电子能量在10~(-7)~10eV内的散射总截面,能量为1.4eV、2.4eV的微分散射截面,计算结果与实验基本符合。本文得到的E=10~(-5)eV处有一总截面极小值σ_(min)=108.61a_s~2,对了解能量低于0.1eV后的散射总截面情况是有益的。 相对论效应对靶原子势场、各散射分波相移、畸变波函数以及总散射截面的影响,本文作了详细讨论,计算结果和讨论表明,即使是慢电子与汞原子弹性碰撞,其相对论效应也是非常重要,应该加以考虑。

The integral and differential cross sections for He-N2 were calculated at a collision energy of 27. 3 meV on the BTT potential energy surface by using the coupled channel (CC) method. The study shows that the calculated total differential cross section is similiar to the experimental one of Fnubel et al. and the state-to-state differential cross sections are not in agreement with the experimental results, as predicted by Bowers et al..

用CC方法计算了在BTT势能面上碰撞能为27.3 meV下He-N_2转动非弹性碰撞截面.研究表明,总的微分碰撞截面与Faubel等的实验结果相似,而态-态微分碰撞截面与实验结果符合欠佳,这与Bowers等的预言一致,
