Cr21+离子1s23d-1s2nf的跃迁能和偶极振子强度
Transition energy and dipole oscillator strength for 1s23d-1s2nf of Cr21+ ion
摘要
Abstract
The transition energy of 1s23d-1s2nf(4≤ n≤9) and fine structure splitting of 1s2nf(n≤9) states for lithium-like Cr21+ ion are calculated by using the full-core plus correlation method. The higher-order relativistic contribution to the energy is estimated under a hydrogenic approximation. The quantum defect of Rydberg series 1s2nf is determined according to the quantum defect theory. The energies of any highly excited states with n≥10 for this series can be reliably predicted using the quantum defects which are function of energy. The dipole oscillator strengths for the 1s23d-1s2nf(n≤9) transitions of Cr21+ ion are calculated with the energies and FCPC wave functions obtained above. Combining the quantum defect theory with the discrete oscillator strengths, the discrete oscillator strengths for the transitions from initial state 1s23d to highly excited states 1s2nf(n≥10) and the oscillator strengths density corresponding to the bound-free transitions are obtained.关键词
