Xe原子的等核及等电子系列离子4f波函数塌缩研究
Theoretical study on the collapse of the 4f wave function in Xe isonuclear and isoelectronic sequence ions
摘要
Abstract
Self-consistent-field calculations of the 4f electron radial wave function for Xe I isonuclear and isoelectronic sequence ions have been made using HFR and LS-dependent HFR methods including correlation and relativistic effects. The collapse behaviors of the 4f wave functions have been studied systematically. The results show that the collapse of the 4f wave function is strongly term dependent. Furthermore, the oscillator strengths of the 4d10→4d9 nf have been computed in Xe-like ions. It is found that the appearance of intense absorption lines in the observed Ba2+ spectrum is due to the partial collapse of the 4f orbital in the 4d→nf1 P channel. It is show that after 4f orbital is completely collapsed for high degrees of ionization along the isolelectronic sequence, the bulk of absorption oscillator strengths is concentrated at the 4d94f1 P level so that the only strong line in the spectrum is again the 4d→4f1P.关键词
