  Benchmarking of evaluated nuclear data libraries was performed for $\sim
14.8$ 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 $\sim 14.8$ MeV neutrons and leakage neutron
energy spectra were measured at 60$^{\circ}$ and 120$^{\circ}$. The measured
spectra are rather well reproduced by MCNP-4C simulations with the CENDL-3.1,
ENDF/B-VII and JENDL-4.0 evaluated nuclear data libraries, except for the
inelastic contributions around $E_{n} = 10-13$ 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.
