摘要
Based on a relativistic Boltzmann-Uehling-Uhlenbeck transport model, proton- and He-3-induced reactions on a Au-197 target at beam energies of 2.8, 5, 10, and 16.587 GeV/nucleon are studied. It is found that compared with proton-induced reactions, He-3-induced reactions give larger cross sections of pion production, about 5 times those of the proton-induced reactions. And more importantly, pion production from He-3-induced reaction is more inclined to low-angle emission. Neutrino production via positively charged pion is also discussed accordingly.
