中文摘要
    本文分别用德拜模型和自洽场离子球模型研究了等离子体中类氦铝离子1snp [n=2-3] (1P1)原子态的能级移动量随电子密度的变化规律,并对二者所计算的能级移动量进行了比较。结果表明:能级移动量随着耦合强度的增大而增大;当耦合强度为一定值时,能级移动量随着电子密度的升高而增大。当电子密度小于1.0×1023cm-3时,不同耦合强度下德拜模型和自洽场离子球模型所计算的能级移动量几乎是相同的。当电子密度大于1.0×1023cm-3时,随着耦合强度的增大,1s2p (1P1)原子态的德拜模型的能级移动量由小于自洽场离子球模型的能级移动量,逐渐转变为大于自洽场离子球模型的能级移动量;1s3p (1P1)原子态的德拜模型的能级移动量始终小于自洽场离子球模型的能级移动量。
英文摘要
    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.
