摘要：

A multi-moderator spectrometer using a pair of Li-6 and Li-7 glass scintillators has been developed. This new type of neutron spectrometer can measure the neutron spectrum in a mixed field of neutrons, charged particles and gamma-rays. The particle identification capability was investigated in neutron-gamma-ray and neutron-proton mixed fields and the neutron response functions of the spectrometer were obtained by calculations and experiments up to 200 MeV. This spectrometer has been applied to measure neutron spectrum in a neutron-proton mixed field? produced by bombarding a Be target by 70 MeV protons from the cyclotron. (C) 2001 Elsevier Science B.V.
