Total kinetic energy release and mass distributions in prompt and delayed muon induced fission of 238U

The time spectra for muon induced fission of 233U, 234U, 235U, 236U, 238U, and 237Npwere measured simultaneously, detecting both fragments in coincidence in a fast multi parallel plate avalanche detector. The observed mean lifetimes r are 68.9___0.3 ns, 70.6+0.2ns, 72.2_0.2ns, 74.3+_0.3ns, 77.0+0.4ns, and 69.8+0.2ns for the above isotopes, respectively. No second time component, tentatively ascribed to a possible fission isomer, was observed. The deduced total capture rates are compared with theoretical predictions.

Mass yield and total kinetic energy release (TKE) distributions of fragments from prompt and delayed muon induced fission, separately, have been measured for the isotopes 23sU, 238U, 23VNp and 242pu. The distributions from prompt muon induced fission are compared with the corresponding distributions from hadronic reactions and from spontaneous fission (s.f.). The distributions from the delayed muonic fission processes are compared to the distributions for neutron and proton-induced fission. No mass distributions measured in the prompt muonic fission process show any signature, which can be attributed to the presence of the muon. Differences observed between the TKE distributions of prompt muon induced and hadron induced fission can be explained Present addresses:
