Note on the Resonance Scattering of High Energyγ-Rays by Nuclei of Carbon and Copper

Abstract

A search has been made for the resonance scattering of high energy $\gamma$-rays in nuclei of carbon and copper using the 100-Mev betatron to provide the primary radiation. The scattering in carbon and copper is less than 1 percent and 3 percent, respectively, of the total cross section for resonance absorption.
