Detailed angular distributions have been measured for /sup 7/Li elastic and inelastic scattering to the first 1/2/sup -/ state in /sup 7/Li (projectile excitation) and the first 2/sup +/, 3/sup -/, and 5/sup -/ states in /sup 40/Ca at E( /sup 7/Li) = 34 MeV. Distorted-wave Born approximation and coupled-channels calculations of the inelastic processes were carried out with both Woods-Saxon and microscopic double-folded real optical potentials. No renormalization of the real double-folded potential is needed to fit the elastic data when the contribution from the ground state quadrupole moment of /sup 7/Li is accounted for in coupled-channels calculations, otherwise a renormalization of 0.6 is required. Moreover, these coupled-channels calculations matched the phase of the oscillations in the projectile excitation data, while calculations employing a Woods-Saxon real potential did not. The calculations for the excitation of states in /sup 40/Ca were insensitive to the form of real potential chosen.
