The hydrogen plasma is studied at temperatures T ∼ 10 4 − 10 6 K using the free energy minimization method. A simple analytic free energy model is proposed which is accurate at densities ρ < ∼ 1 g cm −3 and yields convergent internal partition function of atoms. The occupation probability formalism is modified for solving the ionization equilibrium problem. The ionization degree and equation of state are calculated and compared with the results of other models.PACS numbers: 95.30.Q, 95.30.T, 52.25.K

“…The X-ray opacity of matter under stellar interior conditions and the X-ray diagnostics of ICF plasmas can a e-mail: amar@mpipks-dresden.mpg.de be achieved from such a study [11]. Effect of dense plasma on the ionization potential, collision and photo absorption cross sections, fine structure splitting and spectral line shifts have been investigated earlier by Stewart and Pyatt [13], Rozsnai [14], Ray [15], Jung [16], Griem [17], Siedel et al [18] and Skupski [19]. Applications of density functional approach along this line was reviewed by Gupta and Rajagopal [20].…”

Abstract.A detailed study has been performed for estimating the orbital energies, positions and shifts of the Lyman lines of C 5+ , Al 12+ and Ar 17+ under strongly coupled plasma with a view to understand such line positions and shifts obtained in laser produced plasma experiments. The effect of strongly coupled plasma has been treated within the Ion Sphere (IS) model. Both non-relativistic and relativistic methods have been used for estimating the spectral properties. Theoretical estimates with IS model of the plasma are in conformity with the results of laser plasma experiments on these highly stripped ions. The experimental data for the systems have also been compared with the theoretical estimates using Debye screening model of the plasma with spatial confinements which gives additional restrictions to the wave functions at finite boundaries.

“…We mention that the latter result is different from twice the expression (12). The evaluation of the effective wave equation (15) was given in different papers [28]- [31]. Here the numerical solution of (15) was performed in doing an expansion of the wave function with respect to hydrogenic eigen functions [28], [29].…”
