ABSTRACT

Fractional cumulative yields (FCY) and independent yields (IY) of various fission products in the epicadmium neutron induced fission of 245Cm were measured for the first time by using an off-line γ-ray spectrometric technique. From the FCY values, the isobaric width parameter (σZ), most probable charge (ZP) and the charge polarization (ΔZEXPT) as a function of fragment mass were obtained. The ΔZMPE values based on minimum potential energy surface were theoretically calculated. From the measured IY values, isotopic width parameter (σA), the most probable mass (AP) and the elemental yields (YZ) of Sn, Sb, Te, I, Xe, Cs, Ba, La, Ce and Pr were determined by using a non-linear fit. From the YZ values, the proton even–odd effect (δp) was obtained for the first time. The isobaric and isotopic charge distribution parameters in the 245Cm(nf, f) reaction were compared with the similar data in the thermal neutron induced fission of 245Cm and other actinides to examine the role of excitation energy.
