Abstract

Three γ-decaying isomers in the N=Z+1 nucleus 95Ag have been identified for the first time. The 95Ag nuclei were produced via the 58Ni(40Ca,p2n) reaction and separated by using the GSI on-line mass separator. The emitted γ rays were measured with a multi-Ge detector setup in anticoincidence with positrons. Three individual γ-decay cascades have been identified and assigned to 95Ag, representing the depopulation of isomers at 344-, 2531-, and 4859-keV excitation energy with tentative spin-parity assignments of (1/2),(23/2+), and (37/2+), respectively. The spin and parity assignments are based on a comparison with shell-model predictions employing empirical interactions.
