Neutron Capture Gamma-Rays in Cadmium, Cobalt, and Chlorine

Abstract

A two-crystal scintillation spectrometer has been used to measure the $\gamma$-ray spectra resulting from the thermal neutron capture in ${\mathrm{Cd}}^{113}$, ${\mathrm{Co}}^{59}$, and ${\mathrm{Cl}}^{35}$. Measurements extended over the range of energies from 0.6 Mev to 4.0 Mev. Several prominent $\gamma$-rays were observed. Intensity considerations suggest that cascades involving several of these low energy $\gamma$-rays play a dominant part in the decay schemes.
