“…Another comparison that can be made with reactions induced by different probes on 238 U and 232 Th is the peak to valley ratio (P/V) of the mass distribution, which is an indirect way to interpret symmetric and asymmetric mode contributions for fission. The experimental values obtained in the present work together with data obtained for fission induced by photons [42,43], protons [35,36,45] and neutrons [21,30,44] on the same targets are presented in Fig. 7.…”

In this work we present an analysis of the yields of fission fragments induced by bremsstrahlung photons with endpoint energies of 50 and 3500 MeV on 232 Th and 238 U targets using the simulation code CRISP. A multimodal fission option was added to this code and an extension of the calculation to the properties of the fission products is presented. By dividing the fissioning nuclei according to their fissionability, an approach is introduced which accounts for the contribution of symmetric and asymmetric fission. By adopting this procedure, it was possible to calculate the main parameters for the fission fragment charge distribution such as the most probable charge for a given fission product mass chain and its corresponding width parameter. Also, it was possible to reproduce features of fragment mass distribution and evaluate the fissility of fissioning nuclei for photon-induced fission of 232 Th and 238 U.

“…This discrepancy may be due to a limitation of the model in taking into account all possible channels of decay of the excited nucleus being considered. The peak to valley ratio P/V as a function of excitation energy for fission induced by different probes as photon [42,43], protons [35,36,45] and neutrons [21,30,44]…”

“…The physical cross-sections for high-spin isomer production via spallation of different targets by 600 MeV proton beam have been systematically measured at Dubna, Refs. [21,22]. Definitely, the high yield characterizing spallation reactions was confirmed and quantitatively specified.…”
