Theoretical x-ray transition probabilities for high-Zsuperheavy elements

Abstract

$K$ and $L$ x-ray transition probabilities have been calculated for several elements between $Z=92\mathrm{} \mathrm{and} 170$. The calculations include multipoles higher than $E1\mathrm{}$, are relativistic, and utilize Dirac-Hartree-Fock wave functions with finite-size nuclei. At these very high atomic numbers many transition rates go through a maximum as a function of $Z$, and other transitions show a maximum and a minimum, and then begin to increase again past $Z=150\mathrm{}$.
