The differential cross section angular distribution for 6Li elastic scattering from 28Si was measured at 154 MeV lab energy for center-of-mass angles up to 66°. 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 |V|~120-200 MeV rather than the multitude of discrete parameter families encountered at lower bombarding energies. The best fit to the data selects a |V| 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.
