Elastic scattering of polarized protons from sd and fp shell nuclei has been studied with high-purity germanium detectors. The mean square radius of the central real part of the fitted optical potential was found to be of the form a+bA 2 3. Comparison with the radius from electron scattering gives the range of the effective two-body interaction and its A dependence as 〈r2〉d=(4.5±0.4)+(0.16±0.03)A 2 3 fm2.
