Lifetime Calculations in Quadruply Ionized Lanthanum (La V)

44916

Using the relativistic Hartree-Fock (HFR) method developed by Cowan, the energy levels and lifetimes of 5s^25p^5, 5s^25p^44f, 5s^25p^45d, 5s^25p^46s, 5s^25p^46p, 5s^25p^47s, and 5s^25p^45g configurations of quadruply ionized lanthanum (La V, Z = 57) have been obtained. The Landé g-factors of these levels have been also calculated. In this calculation, configuration interaction and relativistic effects were included and the calculated eigenvalues of Hamilton were improved by fitting the energy levels observed by the least squares method using the available experimental energy levels. We compared our results for energy levels with previously reported the available other works in literature and found it to be quite compatible. These Landé g-factors and lifetime results are reported for the first time in this work. These data are useful for astrophysics and plasma physics.
