The dependence of the differential cross section for the coherent scattering of 1.17 Mev and 1.33 Mev gamma rays on atomic number is investigated. An empirical procedure, which makes an absolute determination of the cross sections unnecessary, is used to eatimate the Compton scattering cross sections. The latter are subtracted from the measured cross sections in order to obtain the relative coherent scattering cross sections, which are found to vary as Z/sup n/. The average value for n is 3.07 plus or minus 0.18. The angular distribution of the total (coherent and Compton) scattering cross section was also investigated in the case of copper and lead between 2.43 deg and 5.79 deg . Results are compared with theoretical predictions and with results of earlier experiments. (auth)
