摘要：

Plastic scintillator (PS) of the new generation was developed for the pulse shape neutron and gamma-quanta discrimination (n/gamma-discrimination). To impart n/gamma discrimination property two activation centers with different decay times were inserted in the PS. One of them transforms singlet excitation into fluorescent light, while the other - makes the same for triplet excitations. 1,4-Dimethy1-9,10-diphenylanthracene and tris(benzoyl-methide) (1,10-phenantroline) Europium III - were used as activators. The figure of merit is 1.48 for this scintillator which is sufficient for reliable n/gamma-discrimination.
