摘要：

The electric microfield distributions at the location of an ion have been calculated using a coupling parameter integration technique for Alkali plasma (Li+, Na+, K+, Rb+, Cs+) proposed by Ortner et al. [1] and Monte-Carlo simulations. Electric microfield distributions are studied in a frame of the Hellmann-Gurskii-Krasko pseudopotential model, taking into account the quantum-mechanical effects and the ion shell structure [2]. For determination of the radial distribution function the screened Hellmann-Gurskii-Krasko pseudopotential in the Debye approximation taking into account not only the quantum-mechanical effects, the ion shell structure but screening field effects has been used [3]. For the Hellmann-Gurskii-Krasko pseudopotential model the results obtained for the microfield in the framework of the Ortner model are found in a good agreement with the Monte-Carlo simulations.
