Physics process of cosmogenics Li-9 and He-8 production on muons interactions with carbon target in liquid scintillator

Abstract

Simulations were performed with GEANT4 to study the cosmogenics Li-9 and He-8 production by the interactions of the muons and their secondary shower particles in the liquid scintillator. The photonuclear reactions seem dominate their production. Their energy dependence were deduced. The comparisons with available data show the reliability of the simulations results.
