Based on fully relativistic HFS self-consistent field AA model, the emerging probabilities of ionic types are determined in analytic formula using the principle of the maximum entropy, and the ionic structures are obtained in peturbation way. All the contributions from over millions of ionic types are taken into account in statistical method according to convolution principle. Finally the formula of extinction coefficient for bound free transition in hot matter with the statistical effects is given, and some results for iron are discussed.

A method based on the Hartree Fock slater self consistent average atom model is employed to calculate opacities of medium and high Z materials. Comparisons with other theoretical results and experiments show that this model is reasonable.

Using the relativistic self-consistent average-atom model,electron scattering resonances in hot plasma have been studied.For AI plasma at solid density and temperature T=10eV,40eV,70eV,100eV,the resonance scattering structure of phase shift,state density and scattering cross section is given,and the influence upon the dlectron conduction produced by resonance scattering is illuminated by comparing the calculated results with experimental ones.

An average-atom(AA) model is employed to calculate differential cross sections for the elastic scattering of electrons from argon and iron plasmas.The results are in good agreement with other theoretical calculations and available experimental data in the low temperature and density limit.Numerical simulations show that the effect from temperature is more complicated than that from density,and differential cross sections change greatly with the condition of the plasma.

This paper is based on the relativistic self-consistent ion-sphere model. The densi-ty and the continuum wave function are determined consistently with the model. The free-free Gaunt factor is calculated by using partial wave phase-shift method, and the results are compared with the predictions of the Born-Elwert approximation.

The GRASP program based on the multi-configuration Dirac-Fock self-consistent method have been extended and revised, so 15 configurations which consist of 89 energy levels in Ne-like titanium ions can be calculated in the same self-consistent process.In the calculations, the averaged level (AL) model and the Fermi two-parameter distribution model of the nuclear volume effect are considered, also Breit correction, vacuum polarization and self-energy effect are counted. LS and jj coupling labels are determined by the maximum combination coefficients. Electric dipole, electric quadrupole and magnetic dipole transition probabilities and oscillator strengths are calculated. The results of oscillator strengths are given in both the Coulomb and the Babushkin gauge, and the electro-dipole oscillator strengths in Babushkin gauge are also compared with the nonrelativistic counterpart.

Schrödinger wave equation is solved for arbitrary matter density and temperature in the Hartree-Fock-Slater (HFS) self-consistent field method. In order to describe relativistic effects, the mass-velocity, the Darwin and spin-orbit coupling terms are included in the wave equation. Some of our results are compared with experimental data and with other theoretical model, the present results are consistent with experiment better and are close to that of Reference.

The purpose of the present work is to provide the immense amount of atomic data needed for applications to the ICF and X-ray laser research work in our institute and for the compilation-evaluation work in Chinese Research Association for Atomic and Molecular Data. Using the non-relativistic Hartree-Fock self-consistent field method including the relaticistic mass-velocity and Darwin terms in the Hamiltonian (HFR) proposed by Dr.R.Cowan, we have calculated atomic structure data and spectroscopic data for the Neon-like FeⅩ Ⅶ, NiⅪ Ⅹ, CuⅩⅩ,GeⅩⅩ Ⅲ and SeⅩⅩ Ⅴ ions. In the calculations the configuration-interaction effects were taken into account. The configuration average energies, 88 energy levels, all possible electric dipole transition wavelengths, oscillator strengths are presented, and in order to discuss the accuracy of the present results we have also compared them with other works.

Schrodinger wave equation is solved in TF Statistical potential including modification of electronic self-interaction for arbitrary temperature and matter density. In order to deal with relativistic effects on atom, relativistic mass-velocity correction, relativistic Darwin correction and spin-orbit coupling correction are introduced into the wave equation. Calculations are presented for Fe, Rb at a few temperature and various densities and comparison with more accurate one's is made in tables. The datas obtained by present method show our results may be compared even with one of relativistic HFS model.
