Polystyrene-based scintillator (PS) with 2-phenyl-5-(4-tert-butylephenyl)-1,3,4-oxadiazole or 2,5-di-(3-methylphenyl)-1,3,4 oxadiazole is proposed for pulse-shape n/γ -discrimination. This scintillator have improved mechanical properties, long operational time and high n/γ -discrimination parameter FOM (1.49 and 1.81 in a wide energy region), so obtained PS can be used as detectors of fast neutrons in the presence of gamma radiation background.
