基于有效相互作用势的稠密半经典等离子体中的动力学电离和复合系数
Kinetic ionization and recombination coefficients in the dense semiclassical plasmas on the basis of the effective interaction potential
摘要：
本文在有效相互作用势的基础上，研究了稠密半经典氢等离子体的电离和复合系数。为此，我们采用Bohr $-$ Lindhard方法和相函数方法，计算了电子俘获和电离截面。在微扰理论的框架下计算了电子俘获截面。有效相互作用势，它考虑到在大距离和短距离的量子衍射效应的屏蔽效应，被使用。研究结果表明，随着等离子体参数的变化，电离系数随密度和（或）耦合参数的增加而减小，而复合系数随密度和（或）耦合参数的增加而增大。
英文摘要：
In this paper, the ionization and recombination coefficients of dense semiclassical hydrogen plasma on the basis of the effective interaction potential have been investigated. For this goal the Bohr$-$Lindhard method and method phase function have been applied to obtain the electron capture and ionization cross sections. The electron capture cross section has been calculated in the framework of the perturbation theory. The effective interaction potential, which takes into account the screening effects at large distances and quantum diffraction effects at short distances, was used. The results of the investigation show the behaviour of the calculated kinetic coefficients with a change in the plasma parameters: the ionization coefficient decreases with increasing density and (or) coupling parameter while the recombination coefficient increases.
