The cumulative and independent yields of various fission products within the mass range of 77–151 have been measured in the , f) reaction by using radiochemical methods together with an off-line -ray spectrometric technique. The post-neutron mass chain yields were obtained from the cumulative fission yields by using charge distribution correction. From the mass yields data, the peak-to-valley (P/V) ratio, full width at tenth maximum (FWTM) of light and heavy mass wing, the average light mass () and heavy mass () as well as the average neutrons number () were obtained. The fine structure of mass chain yield distribution (MD) in the (, f) reaction was explained from the point of nuclear structure effect such as shell closure proximity and even-odd effect. The MD in the (, f) reaction was compared with the MD of (, f) reaction and the role of standard I and standard II asymmetric mode of fission was examined.
