Abstract

The feasible study of Monte Carlo simulation of lowenergy nuclear reaction was performed based on GEANT4. The reaction channel ⁶Li(n， α)³H， simulated insufficiently in the old version Geant4， can be given correct results in the new version (version 4.9.4). New cross section library was added into the program. The study of several nuclear reaction channels shows that the cross sections， the secondary particle energies and the branching ratios are consistent with the experimental values. For doped ⁶Li materials， the comparison of thermal neutrons detection efficiencies of experimental results， MCNP and GEANT4 simulations， shows that the simulations are reasonable. From the studies above， it is feasible to simulate the ⁶Li(n， α)³H reaction with GEANT4. It will provide helpful information for the further study of the position resolution of scintillation neutron detector.
