Possible depletion of isomers in perturbed atomic environments

Abstract

For atomic-nuclear cooperative processes, the cross sections can be deduced in favorable cases from experiments either directly, or through the linked theoretical estimates. Probability of isomer transmutation in electron-assisted mechanisms must contain both nuclear and atomic components. The nuclear database is abundant and extensive, in particular due to the exploration of electromagnetic nuclear processes, like γ-emission, reactions induced by photons, Coulomb excitation and so on. In the present work, the nuclear excitation rate via NEET mechanism is calculated and compared to known experimental results. The NEEC probability is estimated schematically. Perspectives for NEEC detection within different experimental approaches are discussed. A new method is proposed to search for the isomer depletion under stopping of recoiling nuclei in a gas.
