We have measured the inelastic scattering of 35 MeV protons from the nuclei /sup 154/Sm, /sup 176/Yb, /sup 232/Th, and /sup 238/U. Angular distributions were extracted for J/sup ..pi../=0/sup +/--8/sup +/ members of ground state rotational bands. These data were analyzed using coupled channels calculations for scattering from a deformed optical potential. Searches were made on some of the parameters of this potential, including the deformation parameters ..beta../sub 2/ and ..beta../sub 4/. The multipole moments of the potential distribution were calculated from the parameter values and are compared to the results of Coulomb excitation, electron scattering, and inelastic, alpha-particle scattering studies. In general, those moments deduced in our investigation agree better with those from Coulomb excitation and electron scattering than with moments deduced from ..cap alpha..-particle scattering. But we also find the moments from our study to be systematically smaller than those from Coulomb excitation.
