Excitation energies and oscillator strengths for the 1e?‘?2 2e?‘?2 2e?‘?6 3e?‘?2 3e?‘?6 3e?‘‘ 2 e??·e a?’ 1e?‘?2 2e?‘?2 2e?‘?6 3e?‘?2 3e?‘?5 3e?‘‘2 2 e?‘?o, 2e??·o, 2Fo transitions in V4+

摘要

We have calculated the excitation energies (e??￥ e???) and optical oscillator strengths (OOS), of both length (e?‘“L) and velocity (e?‘“e?‘‰) forms, for the 1e?‘?2 2e?‘?2 2e?‘?6 3e?‘?2 3e?‘?6 3e?‘‘ 2 e??·e a?’ 1e?‘?2 2e?‘?2 2e?‘?6 3e?‘?2 3e?‘?5 3e?‘‘2 2 e?‘?o, 2e??·o, 2Fo transitions in V4+ ion of the potassium isoelectronic sequence by employing multicon???guration Hartreea€“Fock (MCHF) method exactly in the same way as we did in our earlier work (Tiwary et al, Pramana a€“ J. Phys. 46, 381 (1996)). We have compared the available relevant experimental data and our earlier theoretical results obtained by employing the con???guration interaction (CI) method (Tiwary et al, J. Phys. B: At. Mol. Phys. 16, 2457 (1983)). Our present investigation clearly demonstrates that the MCHF method is more accurate than the CI method.
