Metastable level properties of the excited configuration 4p⁶4d⁸4f

Abstract

Metastable levels in rhodium-like ions with the ground configuration 4p 6 4d 9 and the excited configurations 4p 6 4d 8 4f and 4p 5 4d 10 are investigated. The ab initio calculations of the level energies, radiative multipole transition probabilities are performed in a quasirelativistic Hartree-Fock approximation employing an extensive configuration interaction based on quasirelativistic transformed radial orbitals. A systematic trends in behavior of calculated radiative lifetimes of the metastable levels are studied for the ions from Z = 60 to Z = 92. The significance of the radiative transitions of higher multipole order (M 2 and E3) for the calculated radiative lifetimes is demonstrated and discussed.

Atomic Data for Zn Ii: Improving Spectral Diagnostics of Chemical Evolution in High-Redshift Galaxies

“…The M1 and E2 radiative transition data are produced for transitions among the levels of the same-parity configurations, and the E1, M2, and E3 transition parameters are produced for the radiative transitions among the levels of the different-parity configurations. The significance of the radiative transitions of higher multipole order, such as M2 or E3, for the radiative lifetimes of some levels was demonstrated by Karpuškienė et al (2013).…”

“…Further, using determined CI wavefunction expansions in the quasirelativistic approximation, transition parameters for electric multipole (E1, E2 and E3) and magnetic multipole (M1 and M2) were produced. The high multiple-order transitions E3 and M2 were determined following the conclusion made in [41] where it was demonstrated that those transitions affect calculated radiative lifetime values of metastable levels. Our calculated radiative lifetimes are presented in Table 1.…”
