Organometallics of the group II, IVA, and VA metals were found to be quenchers for the scintillation process in polyvinyltoluene plastics. Copolymerizing vinyltoluene and p-triphenyltinstyrene produced a slight increase in the degree of quenching above triphenyl-4-ethylphenyltin. In addition, copolymerizing p-triphenylleadstyrene with vinyltoluene also produced slightly more quenching than triphenyl-4-ethylphenyllead physically dissolved in the plastic scintillator. A modified Stern-- Volmer relationship was used to correlate the scintillation quenching of the organometallics and the atomic number. The mechanism of energy transfer and quenching are discussed in relation to the results found in this investigation. (auth)
