摘要：
A description of the 2-pi neutron and gamma-ray multiplicity filter designed as a part of the NORDBALL detection system is given. The filter consists of ten hexagon and six pentagon shaped detectors filled with BC501 liquid scintillator. Individual detector properties as well as system behaviour including neutron scattering are discussed and test results are presented. The properties of the n-gamma pulse shape discriminators used for the system were studied. The discriminators, based on the zero-crossing principle, showed a very efficient separation in the 100:1 dynamic range of neutrons and gamma-rays starting from 70 keV of recoil electron energy. Results from a use of the filter in a study of the Si-28 + Ni-58 reaction are presented.
