We measured the differential cross section for elastic scattering of photons by protons at angles 90° and 150° in the energy interval from 70 to 110 MeV. The experimental data were used to determine the coefficients of the electric and magnetic polarizabilities of the proton, ά=(10.7+1.1)χ 10"3 cm3 and /3 = (-0.7+1.6)Xl0-43 cm3, respectively.
