Abstract

Based on a relativistic Boltzmann-Uehling-Uhlenbeck transport model, proton- and $^{3}$ He-induced reactions on a $^{197}$ Au 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, $^{3}$ He-induced reactions give larger cross sections of pion production, about 5 times those of the proton-induced reactions. And more importantly, pion production from $^{3}$ He-induced reaction is more inclined to low-angle emission. Neutrino production via positively charged pion is also discussed accordingly.
