锂原子能级和光学振子强度的相对论性理论研究
Relativistic treatment for energy levels and oscillator strength of the lithium atom
摘要
Abstract
Relativistic multichannel theory is used to calculate eigen quantum defects of 1s ns S, 1s np P, 1s2nd 2D, and 1s2 nf 2F of lithium, and then the quantum defect functions are fitted. Ionization potentials and quantum defects of 1s np2 P(n=7~60) are obtained, and the results are in good agreement with the latest experiment. Using the relativistic configuration interaction method, the dipole transition oscillator strength of 1s22s-1s2np1/2 are also calculated, and the calculations show that inclusion of one- and two-electron excitation configurations will significantly improve the results.关键词
