Relativistic random-phase approximation calculations on the zinc isoelectronic sequence

Excitation energies, oscillator strengths, and transition probabilities for the $4s^2{}_{}{}^1{}_{}{}^{}S_0^{}{}_{}{}^{}-4s4p{}_{}{}^1{}_{}{}^{}P_1^{}{}_{}{}^{}$, $4s^2{}_{}{}^1{}_{}{}^{}S_0^{}{}_{}{}^{}-4s5p{}_{}{}^1{}_{}{}^{}P_1^{}{}_{}{}^{}$, and $4s^2{}_{}{}^1{}_{}{}^{}S_0^{}{}_{}{}^{}-4s6p{}_{}{}^1{}_{}{}^{}P_1^{}{}_{}{}^{}$ 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.
