Abstract

We report on the nature of ${}^{93 m}{Mo}$ isomer depletion as a result of nuclear excitation by electron capture in a resonant transfer process, accounting for highly excited open-shell atomic states to better reflect realistic beam-based conditions. The improved model provided an enhancement of ${}^{93 m}{Mo}$ depletion. The new probabilities for ${}^{93 m}{Mo}$ isomer depletion are compared with two available experimental results and previous models. The excited-state configurations provide probabilities that are a factor of about 20 higher than those obtained from the ground-state-configuration approach without Compton profiles.
