Independent isomeric yield ratios of <sup>131m,g</sup> Te and <sup>133m,g</sup> Te in the spectrum averaged neutron induced fission of <sup>232</sup> Th
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.
