Effect of a Planckian radiation field on population of bound-electrons

Abstract

The basic atomic physical processes of laser beams interacting with a solid target is checked and the effects of a Planckian radiation field on the population of bound electrons are studied. The results illustrate that the radiation field, if it has a truly Planckian distribution, will influence on the physical processes in plasmas. For instance, it can ensure the distribution of the population on the different ionization stages under the LTE conditions even when the plasmas density is low enough that the collision rates do not dominate over radiative rates.
