【 摘 要 】

We have calculated the excitation energies (𝛥 𝐸) and optical oscillator strengths (OOS), of both length (𝑓L) and velocity (𝑓𝑉) forms, for the 1𝑠2 2𝑠2 2𝑝6 3𝑠2 3𝑝6 3𝑑 2 𝐷e → 1𝑠2 2𝑠2 2𝑝6 3𝑠2 3𝑝5 3𝑑2 2 𝑃o, 2𝐷o, 2Fo 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.
