Abstract
    The variations of the energy level shifts with electron densities of 1snp [n=2-3] (1P1) atomic states for the He-like Al ions in plasmas are investigated by the Debye model and the self-consistent-filed-ion-sphere model, respectively, and the energy level shifts calculated by the two models are also compared. The results show that the energy level shifts increase with the increasing .coupling strength and increasing electron density, when the coupling strength is a fixed value. The energy level shifts under different coupling strengths calculated by the Debye model are almost the same as those by the self- consistent-field-ion-sphere model, when the electron densities are less than 1.0×1023 cm– 3. When the electron densities are greater than 1.0×1023 cm– 3, the energy level shifts of 1s2p (1P1) atomic states with the increasing coupling strength calculated by the Debye model are less at first, and then become greater than those by the self-consistent-field-ion-sphere model. The energy level shifts of 1s3p (1P1) atomic states calculated by the Debye model are always less than those by the self-consistent-field-ion-sphere model.?
