在动态屏蔽势模型下，利用相函数方法研究了部分电离等离子体中电子与原子的弹性散射过程。通过求解Calogero方程计算相移。计算了电子在惰性气体原子上散射的微分截面和总截面，并与实验和其他理论数据进行了比较。结果表明，极化势可以用来描述部分电离等离子体中带电粒子与中性粒子的相互作用。分析结果表明，考虑动态屏蔽后得到的电子原子散射相移比考虑静态屏蔽后得到的相移大。所得结果可用于计算半经典稠密等离子体的各种输运系数。
Within the dynamic screening potential model, elastic scattering processes between electrons and atoms in partially ionized plasmas were investigated using the method of phase functions. The phase shifts were calculated by solving the Calogero equation. Differential and total cross sections for the scattering of electrons on noble gas atoms were calculated and compared with experimental and other theoretical data. It was shown that the polarization potential is adequate for description the interaction between charged and neutral particles in partially ionized plasma. Analysis of the results showed that the phase shifts of electron atom scattering obtained with taking into account the dynamic screening are larger than the data obtained with consideration of static screening. The results can be used to calculate the various transport coefficients of the semiclassical dense plasma.
