| Abstract: | By assuming the ion sphere model, the self-consistent filed model for the Poisson-Boltzmann equation and the Dirac equation is used to calculate the energy levels of He-like chromium in hot and dense plasmas. Consequently, the spectral shifts the intercombination line and the resonance line and the shifts of the exchange energy of He-like chromium in hot and dense plasmas are studied. The results show that the two electric dipole transitions red shift nearly linearly with the increase of plasma electron density. The formula of the linear relationship is found. The results may be useful in developing the new model of dense plasma diagnosis. |
