摘　　要：本文利用等效势模型计算了低能正电子被锂原子弹性散射的散射总截面和微分截面。并将我们的结果和其他计算结果作了比较。Elastic total cross sections and elastic differential cross sections for Positron-Lithium scattering have been calculated using the effective Potential model in the incident energy region 0.5-20,0eV. The results of our calculations have been compared with the corresponding results of other's calculation.
