pHe4Elastic Scattering at 1.05 GeV

Abstract
The angular distribution of the elastic-scattering differential cross section of 1.05-GeV protons by He4 has been measured from 3 to 47° lab. The main features of this measurement are that the first minimum is much less deep than previously measured and that, at the point where a second minimum is predicted by calculations, there is just a slight change of slope.
