Abstract
A high-spin isomer in , of half-life 1.9 (2) , has been observed using the Lohengrin mass spectrometer of the high-flux reactor of the Institut Laue-Langevin, Grenoble. The isomer was produced by the thermal-neutron induced fission of . Measurements at the spectrometer focal point of and , relative to the arrival of a fission fragment, allowed the isomer to be identified and the level scheme constructed. The isomeric state at 6603.3 keV of excitation energy is tentatively assigned a spin and parity of () and is proposed to have a configuration.
