Independent isomeric yield ratios of fission products in the epi-cadmium neutron-induced fission of ${}^{245}$Cm

Independent isomeric yield ratios (IR) of ${}^{128,130,132}$Sb, ${}^{131,133}$Te, ${}^{132,134}$I, ${}^{135}$Xe and ${}^{138}$Cs in the epi-cadmium neutron-induced fission of 245Cm have been measured for the first time by using an off-line gamma-ray spectrometric technique. The average energy of the epi-cadmium neutron spectrum (< E${}_n$ >) is 1.9 MeV. From the IR values, root mean square fragment angular momenta (J${}_{RMS}$) were deduced by using the spin dependent statistical model analysis. The IR and J${}_{RMS}$ values of the fission products from the present work were compared with the literature data in the thermal neutron-induced fission of ${}^{245}$Cm to examine the role of excitation energy. Effect of nuclear structure on J${}_{RMS}$ value was also examined.
