Neutron and Proton Cross-Section Evaluations for²³²Th up to 150 MeV

Theoretical calculations of n+ 232 Th reaction for energies up to 150 MeV

“…The present calculated results of (n, c) and (n, 2n) reactions cross sections are consistent with the Maslov's results (2003,2004). The calculated results of (n, f) reaction cross section are consistent with the evaluated results by Ignatyuk et al (2002), and the results of the energy spectra and double (Baba et al, 1989) and ENDF/B-II at incident energy 2.03 MeV and emission angle 45.0 degree. differential cross sections of emission proton, deuteron, triton and alpha are improved.…”

“…The theoretical calculated results are in good agreement with the experimental data. Ignatyuk et al (2002) have given neutron and proton cross section evaluations for 232 Th up to 150 MeV based on the coupledchannel model and the statistical model of preequilibrium and equilibrium particle emission, with theoretical model parameters adjusted to the available experimental data. For incident neutron energies below 20 MeV the combination of BROND-2 and ENDF/ B-VI evaluations was used.…”

Development of High-Energy BROND Library up to 150 MeV

“…These parameters were used for the calculation of the total, elastic, and inelastic scattering cross sections of 237 Np, 239 Pu, 240 Pu, and 241 Am with the corresponding changes of deformations and coupling schemes. The deformed optical model was also used for evaluations of the elastic and inelastic scattering angular distributions [3][4][5]. The deformed optical model was also used for evaluations of the elastic and inelastic scattering angular distributions [3][4][5].…”

“…In particular, the codes of the intranuclear-cascade model combined with the evaporation model have been successfully applied for the energies above a few hundred MeV. Analogous evaluations for the most important fissile isotopes 232 Th, 238 U, 237 Np, 239 Pu, 240 Pu, and 241 Am have been performed in the Institute of Physics and Power Engineering [3][4][5][6]. For this reason, it was decided that the energy region from 20 to 150 MeV requires special consideration, and the evaluated data files for this energy region should be prepared for the most important structural and fissile materials in the same manner as for the energy region below 20 MeV [1].…”
