Influence of the electronic energy level broadening on the ionization of atoms in hot and dense plasmas: An average atom model demonstration

摘要: The broadening of the electronic energy levels atoms and ions in hot dense plasmas is taken to be an band with a Gaussian distribution density states, which normalized ensure that integration state over one equal statistical weight corresponding atomic level. bound electrons among bands determined by continuum Fermi-Dirac distribution. Within self-consistent field average atom approach, it has been shown explicit considerations for level have significant effects on ionization plasmas. instability pressure induced density, occurs often normal model avoided usually introducing pseudoshape resonance disappears naturally. As examples, dependence Al Au at 1, 10, 100, 1000 eV are presented.
