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 ²⁴¹Pu using an off-line γ-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 <A_L> and heavy mass <A_H>, as well as the average number of neutrons <ν>, were obtained. The mass yields in the epi-cadmium– and thermal neutron–induced fission of ²⁴¹Pu were compared to examine the role of excitation energy on the nuclear structure effect.
