摘要

We have calculated the excitation energies (ΔE) and optical oscillator strengths (OOS), of both length (f L) and velocity (f V) forms, for the 1s 2 2s 2 2p 6 3s 2 3p 6 3d 2 D e → 1s 2 2s 2 2p 6 3s 2 3p 5 3d 2 2 P o, 2 D o, 2 F o transitions in V4 + ion of the potassium isoelectronic sequence by employing multiconfiguration Hartree–Fock (MCHF) method exactly in the same way as we did in our earlier work (Tiwary et al, Pramana – J. Phys. 46, 381 (1996)). We have compared the available relevant experimental data and our earlier theoretical results obtained by employing the configuration 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.
