摘要/Abstract

摘要： 讨论了使用MCHF方法优化径向波函数以获取大量原子参数的方法,由得到的波函数计算了FeXXI离子的相对论与非相对论能级,将计算能级与已有的实验结果进行了比较.对电偶极、磁偶极以及电四极的振子强度进行了非相对论与相对论修正的计算,对非相对论计算的振子强度,长度与速度两种表示符合较好.

关键词: MCHF, 径向波函数, 振子强度

Abstract: Extensive configuration interaction (CI) wave functions are determined using MCHF method and are used to calculate relativistic and non-relativistic energy levels.Agreement is obtained between the calculated and experimental energy levels.Relativistic and non-relativistic electric dipole,magnetic dipole and electric quadrupole oscillator strengths have also been calculated using the CI wave functions.There is a general agreement between the length form and the velocity form.

Key words: MCHF, radial wave function, oscillator strength
