In the epi-cadmium neutron induced fission of U-235, independent isomeric yield ratios (IR) of fission products Sb-130,Sb-132, Te-131,Te-133, I-134,I-136, Xe-135 and Cs-138 have been measured by using an off-line gamma-ray spectrometric technique. The average neutron energy of the epi-cadmium reactor neutron spectrum is 1.9 MeV. From the IR values, the root mean square fragment angular momenta (JRMS) were deduced by using spin dependent statistical model analysis. The IR and JRMS values of considered fission products in the epi-cadmium neutron induced fission of U-235 were compared with the literature data in the thermal neutron induced fission of U-235 to examine the influence of excitation energy on nuclear structure effect.
