摘要

The statistical gamma-ray multiplicity distributions following the reactions Dy-163 (He-3,alpha xn) Dy-162-x and Yb-173 (He-3,alpha xn) Yb-172-x have been studied. The mean value (M) and standard deviation sigma(M) have been extracted as functions of excitation energy. The method is based on the probability distribution of k-fold events, where an alpha-particle is observed in coincidence with signals in k gamma-ray detectors. Techniques for isolating statistical gamma-rays and subtracting random background, cross-talk and neutron contributions are discussed. [References: 22]
