Elastic Scattering of Photons by Protons. I

The results of some preliminary measurements on the elastic scattering of photons by protons are reported. In the region of the (3,3) resonance and immediately above, our measurements join smoothly with those previously reported at lower energies. The scattering cross section shows a peak in the vicinity of 300 Mev. There is indication of a cos²θ term in the center-of-mass angular distribution.
