Electric Microfield Distributions in Li + Plasma With Account of the Ion Structure

The electric microfield distributions at the location of an ion have been calculated using a coupling parameter integration technique for Li + plasma proposed by Ortner et al. [4] and Molecular Dynamics 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 [34]. The screened Hellmann‐Gurskii‐Krasko pseudopotential taking into account not only the quantum‐mecanical effects, the ion shell structure but screening field effects has been derived by means of Bogoljubow method [40] and [42]. The screened pseudopotential is represented by a Fourier transform. 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 Molecular Dynamics simulations (© 2009 WILEY‐VCH Verlag GmbH & Co.
