Abstract
Three -decaying isomers in the nucleus have been identified for the first time. The nuclei were produced via the reaction and separated by using the GSI on-line mass separator. The emitted rays were measured with a multi-Ge detector setup in anticoincidence with positrons. Three individual -decay cascades have been identified and assigned to representing the depopulation of isomers at 344-, 2531-, and 4859-keV excitation energy with tentative spin-parity assignments of and respectively. The spin and parity assignments are based on a comparison with shell-model predictions employing empirical interactions.
