摘要：

We investigated Geant4 Monte Carlo simulation of protons interactions in O-18 and N-14. With proton incident energies of 10 and 30 MeV, we compared the different Geant4 models available for proton inelastic collisions: the low-energy parameterisation, Bertini cascade and precompound models. The models produced different (1) combinations of secondary particles and (2) final states of secondary particles. The non-convergence suggests that the hadronic models, yet to be benchmarked for this energy range, are not ready for production-mode problem-solving. (C) 2008 Elsevier Ltd. All rights reserved.
