摘要 采用相对论多组态自洽场方法,计算了类氦离子Ti20+的精细结构能级以及电偶极、磁偶极和电四极的光谱跃迁波长、跃迁几率和振子强度.计算中考虑了核的有限体积效应、Breit修正和QED修正.计算结果与有关实验测量数据进行了比较. Theoretical wavelengths,transittion probabilities and oscillator strengths for electric dipole,quadrupole and magnetic dipole transitions among some sates of Ti20+ have been calculated by applying the multiconfiguration DiracFock technique with the corrections of finite nuclear size,Breit and QED.The results obtained are in good agreement with the experimental data avaiable.
