低能电子与氮原子弹性散射截面的理论计算

CALCULATION OF CROSS SECTION OF LOW-ENERGY ELECTRON ELASTIC SACTTERING ON NITROGEN ATOM

本文应用等效势模型,计算了能量在0.03—50eV范围内的电子被氮原子弹性散射的总截面、动量转移截面和微分截面,在计算中应用了与入射电子能量有关的不含参数交换势,所得结果比使用与入射电子能量无关的含参数交换势的计算结果更接近实验值。

In this paper, by using the effective potential model, the elastic total, momentum transfer and differential cross sections of low-energy electron scattering on N atom in the range of 0.03-50eV are calculated. In which, due to the exchang potential without a parameter, which is related to the energy of incident electron, being ddopted, the result is closer to the experimental values than the exchange potential with a par-ameter, which is not retated to the energy of incident electron.
