New measurements of inelastic proton scattering to low-lying states of /sup 208/Pb at 200 and 400 MeV are reported. Deformation lengths extracted from angular distributions for the 3/sup -/ (2.614 MeV), 5/sub 1//sup -/ (3.198 MeV), 5/sub 2//sup -/ (3.209 MeV), 2/sup +/ (4.086 MeV) and 4/sup +/ (4.324 MeV) states are in good accord with values extracted at other incident proton energies. The fact that the deformation lengths are independent of incident proton energy within experimental uncertainty provides support for the validity of the collective DWBA for medium energy proton scattering to strongly excited states. Advantage is taken of this to extract statistically more precise values of the ratio of neutron to proton multipole matrix elements (M/sub n//M/sub p/). Different methods of determining the appropriate average value of M/sub n//M/sub p/ are discussed. 3 refs., 1 tab.
