Abstract
A liquid scintillation spectrometer comprises two PM detectors, a circuit for detecting prompt coincidences between the signals from the detectors and a circuit for detecting delayed coincidences. Counting means controlled by the coincidence circuits detect the excess of the occurrences of prompt coincidences over delayed coincidences and count that excess in real time.
