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 (© 2009 WILEY‐VCH Verlag GmbH & Co.
