Abstract

Differential cross sections for the elastic scattering of $^{4} He$ from $^{4} He$ 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.
