Abstract

Plasma can be produced using different schemes based on ionization processes of a neutral gas. Recently, it was demonstrated that due to collective effects the ionization potential of chemical elements can be changed particularly for a dense plasmas. We investigated this characteristic for monoatom gases and found that the critical density for which these effects are significant is no 1013 cm−3.The latter depends on atom’s ionization energy. It is also found that this effect can only be observed for a certain range of density and temperature related to the first ionization potential of the chemical element.
