Quasielastic yields have been measured for the /sup 28/Si+ /sup 208/Pb reaction at E/sub lab/( /sup 28/Si) = 225 MeV. The inelastic scattering is dominated by excitation of the first 2/sup +/ level in /sup 28/Si. The angular distribution for this state is found to contain insufficient information to determine accurately the quadrupole deformation parameter once the possibility of hexadecapole deformation is admitted. The ambiguity is resolved by requiring a simultaneous fit to the angular distribution of the first 4/sup +/ state in /sup 28/Si. A large fraction of the total reaction cross section is found to be contained in quasielastic neutron transfer, and transfer of a single proton. It is shown that these large quasielastic yields are consistent with the expectations from distorted-wave Born approximation calculations.
