Abstract

A multiple detector system for γ - γ coincidence and angular correlation measurements is described. The system consists of four large coaxial Ge detectors set at fixed positions, enabling the measurement of γ - γ coincidences between any pair. Thus, six distinct angles are measured simultaneously. The performance of the system was studied with a 152Eu source. An application for γ - γ correlation studies in 146Ce is described. Systematic errors, if present, are shown to be less than 0.03 and 0.05 for A2 and A4, respectively. The extension of this system to more than four detectors is straightforward.
