Independent isomeric yield ratios of fission products in the epi-cadmium neutron-induced fission of 245Cm.

Independent isomeric yield ratios (IR) of ^128,130,132Sb, ^131,133Te, ^132,134I, ¹³⁵Xe and ¹³⁸Cs 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 ²⁴⁵Cm to examine the role of excitation energy. Effect of nuclear structure on J_RMS value was also examined. [ABSTRACT FROM AUTHOR]
