Abstract：
A new method used to discriminate neutrons and photons in liquid scintillators with charge comparison and using a CAMAC-microcomputer data acquisition system is described. The total charge and multi-channel partial charges for different time segments of pulses from liquid scintillator samples of NE213 or BC519 radiated by ²⁴¹Am-Be or ²⁵²C_f neutron sources are measured. The dependences of n,γ seperation in scintillators on delay time and energy distribution are given from off-line data analysis. The energy distribution of neutrons or γ-ray and pulse shapes for fast and slow components of scintillators can be measured using such a n, γ discrimination method.
