Abstract
Electron-capture delayed fission of produced via the reaction at 87 MeV (on target) was observed to decay with a half-life of consistent with the reported α-decay half-life of of The mass-yield distribution of the fission fragments is highly asymmetric. The average pre-neutron emission total kinetic energy of the fragments was measured to be Based on the ratio of the measured number of fission events to the measured number of α decays from the electron-capture daughter (100% α branch), the probability of delayed fission was determined to be This value for the delayed fission probability fits the experimental trend of increasing delayed fission probability with increasing Q value for electron capture.
