| abstract in english: | The polystyrene doped with 2,5-diphenyloxazole as a primary fl uor and 2-(4-styrylphenyl)benzoxazole as a wavelength shifter prepared as a plastic scintillator was investigated using positronium probe in wide range of temperatures from 123 to 423 K. Three structural transitions at 260, 283, and 370 K were found in the material. In the o-Ps intensity dependence on temperature, the signifi cant hysteresis is observed. Heated to 370 K, the material exhibits the o-Ps intensity variations in time |
