Distinguishing fissions of 232Th, 237Np and 238U with beta-delayed gamma rays
Measurements of beta-delayed gamma-ray spectra following 14-MeV neutron-induced fissions of 232Th, 237Np, and 238U were conducted at Lawrence Berkeley National Laboratory's 88-Inch Cyclotron. Spectra were collected for times ranging from 1 minute to 14 hours after irradiation. Intensity ratios of gamma-ray lines were extracted from the data that allow identification of the fissioning isotope.
