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 152 Eu source. An application for γ - γ correlation studies in 146 Ce is described. Systematic errors, if present, are shown to be less than 0.03 and 0.05 for A 2 and A 4 , respectively. The extension of this system to more than four detectors is straightforward. © 1983.
