Analytic model for the lowering of the ionization potentials of atoms and ions in a collisional plasma

  • S. I. Anisimov
  • Yu. V. Petrov


A model admitting of an analytic solution is developed for the calculation of the level shift and the reduction of the ionization potentials of atoms and ions due to screening in a collisional plasma. The application of the derived equations to the plasmas of aluminum, gold, copper and cesium shows the greatest reduction in the ionization potential occurs for cesium.
