| 摘 要： | Based on the detailed configuration accounting(DCA) model,a method is developed to include the resonant photoionization and the excitation-autoionization in the non-local thermodynamical equilibrium (NLTE) average atom (AA) model.Using this new model,the mean charge states and the opacity are calculated for NLTE high-Z plasmas and compared with other results.The agreement with AA model is poor at low electron density.The present results agree well with those of DCA model within 10%.The calculations show that the NLTE effects on opacity are strong.

| Abstract: | Based on the detailed configuration accounting (DCA) model, a method is developed to include the resonant photoionization and the excitation-autoionization in the non-local thermodynamical equilibrium (NLTE) average atom (AA) model. Using this new model, the mean charge states and the opacity are calculated for NLTE high-Z plasmas and compared with other results. The agreement with AA model is poor at low electron density. The present results agree well with those of DCA model within 10%. The calculations show that the NLTE effects on opacity are strong. |
