摘要
采用全实加关联方法研究了高离化MnXXIII离子1s^(2)nl(l=s,p)态的能量,研究了1s^(2)n′s(2≤n′≤5)态-1s^(2)np(2≤n≤9)态之间的跃迁能和跃迁波长,将本次研究得到的计算结果与已有的实验数据和理论数据进行比对,发现它们之间具有相当高的一致性。在本次研究中,考虑了高阶相对论效应的贡献来提高计算的精度。将全实加关联方法电离能的结果与半经验电离能结果进行比较,由此推断出用作为能量的缓变函数的量子亏损,可以实现对任意高激发态(n≥10)能量的可靠预言。
The full-core-plus-correlation method is used to study the energy of the 1s2nl(l=s,p)states of the highly charged ion for MnXXIII.The transition energies and transition wavelengths between the 1s2n′s(2≤n′≤5)states and 1s2np(2≤n≤9)states are also calculated.The calculated results are compared with the existing experimental data and theoretical data,and it is found that they have a very high consistency.The contribution of higher-order relativistic effect is considered to improve the accuracy of calculation.The ionization energy results using the full-core-plus-correlation method are compared with the results using the semi-empirical method.It is deduced that the quantum defect used as a slowly varying function of energy can achieve a reliable prediction of the energy for any highly excited state(n≥10).
