Angular Momentum Selection Using Total Gamma-Ray Energies

Abstract
Use of a total γ-energy spectrometer in coincidence with a variety of detectors has led to the observation of the highest multiplicities yet achieved for compound nuclear products, allowing for the selection and study of high angular momentum states. A differential comparison of coincident γ spectra corresponding to slices of the total-energy spectrum yields a direct evaluation of the moment of inertia for a rotational nuclear structure.
