    Research output: Contribution to journalJournal articlepeer-review


    The 116 ns shape isomer in 236U was populated by thermal neutron capture. Conversion electrons and X-rays were detected simultaneously in delayed coincidence with fission. The ratio of delayed to prompt fission was measured with the result, σIIf/σf = (1.0±0.2) × 10−5. A branching of the isomeric decay σIIγ/σIIf = 7±2 was deduced from this number. No definite electron line structure was observed.
