Post-Neutron Mass Yield Distribution in the Epi-Cadmium Neutron-Induced Fission of Pu-241

The cumulative and independent yields of various fission products within the mass range of 83 to 117 and 123 to 157 have been measured in the epi-cadmium neutron-induced fission of Pu-241 using an off-line ?-ray spectrometric technique. From the cumulative yields, post-neutron mass yields were obtained using the charge distribution correction. The full-width at tenth maximum of the light and heavy mass wings and the average light mass and heavy mass , as well as the average number of neutrons , were obtained. The mass yields in the epi-cadmium- and thermal neutron-induced fission of Pu-241 were compared to examine the role of excitation energy on the nuclear structure effect.
