摘要：

The discrimination of neutron and gamma-ray events in an organic scintillator with the pulse gradient analysis (PGA) method is verified against that achieved via the digital measurement of time of flight (TOF). Events arising from the (7)Li(p,n)(7) Be reaction have been detected with an LS-301 organic liquid scintillator and recorded with a fast digital sampling oscilloscope. Both qualitative (via the cross-referencing of scatter diagrams) and quantitative (via the neutron/gamma-ray ratio) comparisons are reported. Discrimination afforded by the PGA method is observed to be consistent with that achieved by digital TOF. (c) 2007 Elsevier B.V. All rights reserved.
