Independent isomeric yield ratios of 131m,g Te and 133m,g Te in the spectrum averaged neutron induced fission of 232 Th
Abstract
Abstract In the 4.93, 6.61, 8.31 and 10.92 MeV spectrum averaged neutron-induced fission of 232 Th, independent isomeric yield ratios (IR) of the fission products 131m,g Te and 133m,g Te have been experimentally determine. An off-line gamma-ray spectrometric technique was used for the measurement. The average neutron energies used were obtained from the 7 Li(p, n) reaction by using the proton energies of 7, 11, 15 and 18.8 MeV. From the IR values, the root mean square fragment angular momenta ( J RMS ) were deduced by applying spin dependent statistical model analysis. The effect of nuclear structure and role of excitation energy on the IR and J RMS values of 131m,g Te and 133m,g Te were examined.
