Theoretical analysis of double-differential cross sections of proton, deuteron, and triton emission in the p + Li-7 reaction at 14 MeV

摘要

Based on the statistical theory of light nucleus reactions, the description of the complicated emission processes of proton and light composite charged particles are further improved through considering the effects of Coulomb barriers both in incident and different outgoing reaction channels. Moreover, the analysis of the reaction channels including the sequential and simultaneous emission processes for p + Li-7 reaction is performed in detail. So the partial spectra of all of outgoing particles are also obtained for different reaction processes. The calculated double-differential cross sections of total outgoing proton, deuteron, and triton at E-p = 14 MeV agree well with the available experimental data for different outgoing angles. The ENDF-6 formatted data, which includes all of the reaction cross sections, elastic angular distributions, double-differential cross sections of nucleon, and light composite charged particles for the p + Li-7 reaction, are also obtained by PUNF code.
