【摘要】 |
|
The ionization potentials and fine structure splittings of 1s2nl (l = s, p, and d; n≤9) states for lithium-like V20+ ion are calculated by using the full-core plus correlation (FCPC) method. The quantum defects of these three Rydberg series are determined according to the single-channel quantum defect theory (QDT). The energies of any highly excited states with n≥10 for these series can be reliably predicted using the quantum defects that are function of energy. The dipole oscillator strengths for the 1s22s–1s2np and 1s22p–1s2nd (n≤9) transitions of V20+ ion are calculated with the energies and FCPC wave functions obtained above. Combining the QDT with the discrete oscillator strengths, the discrete oscillator strengths for the transitions from the given initial state to highly excited states (n≥10) and the oscillator strength density corresponding to the bound-free transitions are obtained. |
