High-spin μs isomeric states in 96Ag

Abstract

The isomeric and β decays of the N = Z +2 nucleus 96Ag were investigated at NSCL. A cascade of γ-ray transitions originating from the de-excitation of a μs isomer was observed for the first time and was found in coincidence with two previously-known transitions with energies of 470 and 667 keV. The isomeric half-life was determined as 1.45(7) μs, more precise than previously reported. The existence of a second, longer-lived μs isomer, associated with a 743-keV transition, is also proposed here. Shell model results within the (p_{3/2}p_{1/2}f_{5/2}g_{9/2}) model space, using the jj44b interaction, reproduced level energies and isomeric decay half-lives reasonably well.
