The absolute cumulative fission yield of 140Ba and the relative yields of 131I, 132Te, and 141Ce were measured for 232Th irradiated in a 252Cf fission spectrum of neutrons. The irradiation was performed using two 232Th foils in contact with a nominal 1-mg 252Cf source in a large evacuated area for 41 days. The absolute yield of 140Ba was deduced from an absolute measurement of its daughter product 140La using a calibrated NaI(Tl) detector. The activities of 131I, 132Te, and 141 Ce were measured relative to the 1596-ke V gamma ray of 140La using a 43-cm3 Ge(Li) detector. The fission rate for the yield measurement and the integral fission cross section were measured using mica solid-state track recorders.
