Evaluating four neutron-gamma discrimination methods with EJ-301 scintillator

The penetration of gamma in neutron spectra reduces the accuracy of measurement results, especially when using the scintillation detector. The digital method can be used to identify either neutron or gamma pulses. In order to select the algorithm for detector using EJ-301 liquid scintillator (EJ-301...
