Distinguishing fissions of 232Th, 237Np and 238U with beta-delayed gamma rays
Published Web Locationhttps://doi.org/10.1016/j.nimb.2013.03.054
Measurements of beta-delayed gamma-ray spectra following 14-MeV neutron-induced fissions of 232Th, 238U, and 237Np were conducted at Lawrence Berkeley National Laboratory's 88-Inch Cyclotron. Spectra were collected for times ranging from 1 min to 14 h after irradiation. Intensity ratios of gamma-ray lines were extracted from the data that allow identification of the fissioning isotope.© 2013 Elsevier B.V. All rights reserved.
