Neutrons within energy range of 5 to 300 keV can be produced by pulsed proton beam striking thick lithium target,based on the HI-13 tandem accelerator.Neutron shielding is necessary when the Gamma-ray Total Absorption Facility(GTAF)is applied to measured(n,γ)reaction cross sections Neutrons within energy range of 5 to 300 keV can be produced by pulsed proton beam striking thick lithium target, based on the HI-13 tandem accelerator. Neutron shielding is necessary when the Gamma-ray Total Absorption Facility (GTAF) is applied to measured ( n, γ) reaction cross sections
