The scattering cross sections of l.33-Mev Mev gamma rays were measured in tin for angles between 20 and 115 deg and in uranium and lead at 20 deg . The ratio of the scattering cross seetioiis for 1.17- and 1.33-Mev radiations from Co/sup 60/ and the scattering cross section of Zn l.l2-Mev gamma rays were determined. The experimental values are in good agreement with the curves derived from complete calculations for the terms relative to the absorption and reemission oi photons by the electron cortege. The bonding of these electrons in the intermediate stute was considered. The method and apparatus used for the measurements are described in detail. 78 references. (J.S.R.)
