The differential cross section angular distribution for /sup 6/Li elastic scattering from /sup 28/Si was measured at 154 MeV lab energy for center-of-mass angles up to 66/sup 0/. The data exhibit forward-angle diffractive structure and a large-angle falloff similar to that of refractive nuclear scattering. An optical-model analysis with Woods-Saxon form factors and standard fitting criterion yields a broad continuum of admissible real central potential depths vertical-barV vertical-bar approx. 120--200 MeV rather than the multitude of discrete parameter families encountered at lower bombarding energies. The best fit to the data selects a vertical-barV vertical-bar near 160 MeV. A Woods-Saxon squared form factor as well as a microscopic folding-model potential have also been investigated in fitting the data.
