    • Total excitation energy distribution for neutron-induced fission of thorium isotopes


      More Details Abstract Fulltext PDF

      The fission fragment total excitation energy, TXE(A), was calculated for neutron-induced fission of $^{227−233}$Th using three methods. The first method is the conventional method of calculating TXE by subtracting Q value from total kinetic energy value. The second method is usually used to calculate the number of neutrons emitted and the third method is a systematic method by applying the intrinsic energy within the statistical scission point model. Third method has been modified based on the results of the other two methods and the required parameters have been obtained from neutron-induced fission of $^{232}$Th to calculate TXE distribution for other thorium isotopes. This indicates that for all thorium isotopes, TXE values increase with increasing mass numbers of fission fragments, except for the fission fragments with mass number about 95–100.
