Relativistic random-phase approximation calculations on the zinc isoelectronic sequence

Abstract

Excitation energies, oscillator strengths, and transition probabilities for the $4{s}^{2}^{1}S_{0}\ensuremath{-}4s4p^{1}P_{1}$, $4{s}^{2}^{1}S_{0}\ensuremath{-}4s5p^{1}P_{1}$, and $4{s}^{2}^{1}S_{0}\ensuremath{-}4s6p^{1}P_{1}$ resonance transitions of elements of the zinc isoelectronic sequence are calculated using the relativistic random-phase approximation. The elements considered range from Gaii to Ulxiii and include many of interest in current fusion research. A graphical analysis of the systematic trends of the oscillator strength as a function of the inverse nuclear charge provides a means of estimating the oscillator strengths for those elements whose values are not explicitly calculated.
