Effective statistical weights of Rydberg orbitals of dopant Ar in dense plasmas and their effect on higher order satellite lines

Abstract

Calculated are the effective statistical weights of Rydberg orbitals of dopant Ar ions in dense hydrogen plasmas. Energy levels are shifted due to the screening of the nuclear Coulomb potential and the Stark effect. The electric microfield distribution is evaluated by using the adjustable-parameter exponential approximation. The Ryberg orbitals are easily ionized not only by the continuum lowering but also by the plasma electric microfield. The statistical weights of high-lying orbitals are strongly influenced by surrounding charged particles. The results of present calculations are compared with More’s empirical formula, and it is found that the effective statistical weights of Rydberg orbitals remain higher than those predicted by More’s formula.
