Description

Time distributions of fragments from delayed fission after muon capture have been measured for muonic 235U, 238U, 237Np, 239Pu, and 242Pu. Comparison of these data with previously measured lifetimes using muon decay electrons, neutrons, and γ rays emitted after muon capture indicates that the observed systematic discrepancies are due to atomic muon capture by fission fragments after prompt fission induced by radiation-less muonic transitions. The deduced capture rates are compared with theoretical models, and very good agreement is found with a giant-resonance excitation model
