Differential cross sections and analyzing powers for elastic scattering of 17-MeV polarized tritons from /sup 26/Mg, /sup 27/Al, and /sup 28/Si were measured in the angular range 20/sup 0/ to 160/sup 0/. Significant target dependence of the analyzing power was observed, and reaction mechanisms other than shape-elastic scattering appear to contribute at large scattering angles. An optical-model analysis of these data was carried out to determine potential parameters that fit both observables simultaneously. The central potentials are reasonably well defined by the data, but strong absorption limits our ability to determine reliably the parameters of the spin-orbit potential; at the present low triton energy, the scattering appears to be sensitive predominantly to the spin-orbit strength in the outer surface region of the nucleus.
