Benchmarking of evaluated nuclear data libraries was performed for ∼14.8 MeV neutrons on Gallium targets. The experiments were performed at China Institute of Atomic Energy (CIAE). Solid samples of natural Gallium (3.2 cm and 6.4 cm thick) were bombarded by ∼14.8 MeV neutrons and leakage neutron energy spectra were measured at 60° and 120°. The measured spectra are rather well reproduced by MCNP-4C simulations with the CENDL3.1, ENDF/B-VII and JENDL-4.0 evaluated nuclear data libraries, except for the inelastic contributions around En=10–13 MeVEn=10–13 MeV. All three libraries significantly underestimate the inelastic contributions. The inelastic contributions are further studied, using the Talys simulation code and the experimental spectra are reproduced reasonably well in the whole energy range by the Talys calculation, including the inelastic contributions.
