The study of prompt and delayed muon induced fission

Abstract

The ratios of prompt to delayed fission yields for the isotopes 233U, 234U, 235U, 236U, 238U, 237Np, 242pu, and 244pu and the fission probabilities relative to each other have been investigated experimentally. Using the value of the total fission probability for 237Np the absolute probabilities for prompt and delayed fission have been determined. The fission probabilities per muon capture P1~ have been derived for all the isotopes and compared with an evaluation based on excitation functions from theory.
