Abstract
In this work the microsecond isomers in and were investigated. These nuclei were produced by the thermal-neutron-induced fission of The detection is based on a time correlation between the fission fragments selected by the LOHENGRIN spectrometer at the ILL (Grenoble) and the rays or conversion electrons from the isomers. The decay schemes of the new isomer in and isomer in are reported. A shell-model study of these two nuclei was performed using a realistic effective interaction derived from the CD–Bonn nucleon-nucleon potential. Comparison shows that the calculated energy levels and electromagnetic transition rates are in very good agreement with the experimental data.
