Hyperfine Quenching of the $4s4p^3{P}_0$ Level in Zn-like Ions

Abstract

In this paper, we used the multiconfiguration Dirac-Fock method to compute with high precision the influence of the hyperfine interaction on the $[Ar]3d^{10}4s4p^3{P}_0$ level lifetime in Zn-like ions for stable and some quasi-stable isotopes of nonzero nuclear spin between Z=30 and Z=92. The influence of this interaction on the $[Ar]3d^{10}4s4p^3{P}_1-[Ar]3d^{10}4s4p^3{P}_0$ separation energy is also calculated for the same ions.
