Abstract
The ratio of 133Xe isomers produced in the fission of 232Th, 233U, 235U, and 238U by protons ranging in energy from 20–85 MeV was measured. The Hafner, Huizenga, and Vandenbosch formalism was applied with different sets of input parameters to establish their effect on the relation between initial fragment spin and isomer ratio for three spin-pair classes of isomers. The isomer ratio was found to be independent of the spin and type of fissioning target and only weakly dependent on projectile energy.Keywords
