We have measured the inelastic scattering of 35-MeV protons from /sup 232/Th and from /sup 234,236,238/U. Angular distributions were extracted for J/sup ..pi../ = 0/sup +/--8/sup +/ members of the ground-state rotational bands, and were analyzed with use of coupled-channels calculations for scattering from a deformed optical potential. The deformation parameter ..beta../sub 6/ is positive for /sup 232/Th and /sup 234/U, nearly zero for /sup 236/U, and negative for /sup 238/U. The trends of the deformation parameters and multipole moments are explained qualitatively by a simple model.
