Abstract
Abstract WHEREIN A1 is a branched chain alkyl, B1 is hydrogen, phenyl, lower alkyl, or lower alkoxy, and m is 1 or 2. The counts per minute emitted by the material dispersed in the scintillation liquid are measured with a suitable instrument such as a liquid scintillation spectrometer. The invention relates to a composition of matter for counting atomic disintegrations of radioactive material which is accompanied by emission of Beta -rays which contains an oxdiazole compound of the formula
