Elastic Scattering of 9.76-Mev Protons by Helium

Abstract

The differential cross section for elastic scattering of 9.76-Mev protons by helium has been investigated over the range of center-of-mass angles from 43° to 174°. The results are in essential agreement with those of Putnam at 9.48 Mev, differ from those by Freemantle et al. at 9.55 Mev by a constant factor, but do not confirm those of Cork and Hartsough at 9.7 Mev.
