Elastic p-p scattering was investigated by the emulsion method at an energy of 8.5 Bev. The geometry of exposing was usel at which the beam of incident protons is directed perpendicular to the emulsion plane. All in all, 480 events of elastic scattering were found. The total cross section for elastic scattering is equal to 8.74 plus or minus 0.40 mb. The differential cross section was investigated in the angle interval of 1.5 to 20.5 deg in the c.m.s. The experimental data are in agreement with the simple nucleon model in which the real part of the phase shifts and the dependence of the interaction cross section on the spin state is neglected. The total p-p interaction cross section calculated under these assumptions from the experimental data obtained in this investigation is greater than that measured experimentally by a threefold error. In order to answer the question whether this is due to the real part of the scattering amplitude or its dependence on the spin state a considerably higher accuracy is necessary. One can, however, assert that the real part of the scattering amplitude does not exceed 0.5 lm f( theta ). The root-mean-square radius of the proten-proton interaction is found to be equal to 1.15 plus or minus 0.05 f. (auth)
