Mass yield distribution in the fission of ${}^{244}$Cm induced by a spectrum of epi-cadmium to fast neutron

The cumulative yields of various fission products within the mass range of 83-119 and 123-158 as well as independent yields of few fission products in the fission of ${}^{244}$Cm induced by a spectrum of epi-cadmium to fast neutron have been measured by using an off-line γ-ray spectrometric technique. Charge distribution correction was applied on the cumulative yields to obtain the post-neutron mass yields of fission products. The peak-to-valley (P/V) ratio, the full width at tenth maximum (FWTM) of light and heavy mass wing, the average light mass (L>) and heavy mass (H>) as well as the average number of neutrons (<ν>) were obtained from the mass yield distribution. The mass yield data in between the ${}^{244}$Cm(n, f) and ${}^{245}$Cm(n${}_{th}$, f) reactions were compared to examine the role of small difference of excitation energy on P/V ratio and nuclear structure effect as well as on the standard I and standard II asymmetric modes of fission.
