Abstract
Differential cross sections for the elastic scattering of He-4 from 4He hav e been measured at 280 and 620 MeV. The data exhibit systematic energy depe ndence when compared with measurements at lower energies. Optical model ana lysis indicates that the Woods-Saxon potential fails to reproduce the large angle data. Satisfactory fits are obtained by adding a Woods-Saxon squared form factor to the real central potential.
