Abstract
The cumulative yields of various fission products and independent yields of few fission products within the mass range of 78–153 have been measured in the epi-cadmium neutron-induced fission of 232Th by using an off-line γ-ray spectrometric technique. Charge distribution correction on the cumulative fission yields was applied to obtain the post-neutron mass chain yields. The peak-to-valley (P/V) ratio, full width at tenth maximum (FWTM) of light and heavy mass wing, the average light mass (<AL>) and heavy mass (<AH>) as well as the average number of neutrons (<ν>) emitted were obtained from the mass chain yields. The fission yield data in the 232Th(n, f) reaction were compared with the literature data as well as with the similar data in the 229Th(nth, f) reaction to examine the effect of nuclear structure and the role of standard I and standard II asymmetric mode of fission.
