S>A description is given of an apparatus used to distinguish the fast neutron pulses from a Po- Re source from a natural gamma background or produced with Cs/sup 137/, Ra, or Th sources. From the experiments information was obtained on the emission characteristics of various scintillators excited by neutrons. The results, which are tabulated, show that in the scintillations preduced by recoil protons the fraction of light emitted beyond a time, which is a characteristic of the scintillator used, is appreciably greater than in the case of excitation by electrons. This slow component of the scintillation can be used to discriminate neutrons from a gamma background. (J.S.R.)
