Abstract
- Relativistic photoionization processes of an exemplary highly charged H-like ion Ar<superscript>17+</superscript> for 1s<subscript>1/2</subscript>, 2l<subscript>j</subscript> (l = 0, 1), and 3l<subscript>j</subscript> (l = 1, 2) initial states are studied in plasmas with coulomb coupling parameter 0.007 < Γ < 0.202. Photoionization cross sections for both the strongly and weakly screened cases exhibit specific properties when their plasma densities and temperatures in the vicinities of the critical values at which nlj bound states enter the continuum. The electron degeneracy, finite-temperature gradient corrections, and quantum exchange-correlations effects have been included in the interaction between charged particles by the screened potential used in the present work. It is found that these effects for the plasmas with different coupled strength are reflected in the resonant regions of photoionization cross sections by comparing with Debye cases. The present work is expected to provide theoretical and data support for the fusion plasmas. [ABSTRACT FROM AUTHOR]
