Abstract
THE determination of all but the simplest radioactive decay schemes necessitates a means of analysis of the γ-rays emitted, so that coincidences may be measured between the various γ-rays, and also between a particular γ-ray and the primary β-ray spectrum. Many nuclei emit γ-rays well spaced in energy, and a spectrometer of quite poor resolution would separate them sufficiently well for coincidence measurements. It has been known for some time that organic crystal scintillation counters act proportionally for α-particles1. The present work shows that such a counter may also be used as a crude γ-ray spectrometer, with an extremely high efficiency.
