Polystyrene and deuteropolystyrene plastic scintillators for a polarized active target

Results of light output measurements for a polystyrene scintillator deutera ted to a degree of 96 at. % are presented. Applications of the deuterated s cintillator are considered, in particular, as an active detector. In order to polarize the hydrogen nuclei in the scintillation target, a special addi tive, 2,2,6,6-tetramethyl-piperidine-1-oxyl (TEMPO), was introduced into it . This resulted in a light output of the sample with a thickness of 3.6 min 50% that of the initial sample.
