DIFFERENTIAL CROSS SECTIONS IN PROTON--PROTON SCATTERING AT 52.34 MeV.

Abstract A measurement of differential cross sections in proton-proton scattering at 52.34 MeV, of a higher precision than that of the measurement of 1961 was made at 29 angles from 14° to 90° c.m. angle. A large scattering chamber of sliding-cylinder type, hydrogen gas target and NaI(Tl) detectors were used. The total error of the differential cross sections was ±0.5% over most of the angular range. The agreement of the present results with recent results at 49.41 MeV is very good in the angular range greater than 20° c.m. angle in spite of the difference in method.
