Distinguishing fissions of $$^{232}$$Th, $$^{237}$$Np and $$^{238}$$U with beta-delayed $$gamma$$ rays

Measurements of beta-delayed $$gamma$$-ray spectra following 14-MeV neutron-induced fissions of $$^{232}$$Th, $$^{238}$$U, and $$^{237}$$Np 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.
