Differential cross sections for the elastic scattering of 4He from 4He have been measured at 280 and 620 MeV. The data exhibit systematic energy dependence when compared with measurements at lower energies. Optical model analysis 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.
