Excitation functions have been measured for the elastic and inelastic scattering of polarized protons from /sup 206/Pb at theta/sub lab/ = 120/sup 0/, 135/sup 0/, 150/sup 0/, and 165/sup 0/ in the energy range E/sub p/ = 14.25--18.00 MeV. Excellent fits to the elastic scattering data were obtained using a parametrized background and the isobaric analog resonances of 35 states in /sup 207/Pb (the ''parent states'') with E/sub x/ = 2.3--5.7 MeV; spin-parity assignments and resonance parameters were determined for all of these isobaric analog resonances. The data for inelastic scattering to the first excited state (2/sup +/, 0.803 MeV) were described using a distorted-wave Born approximation background and the same isobaric analog resonances; good fits to the data were obtained by varying only the inelastic partial width amplitudes. A set of spectroscopic amplitudes was then found, for both the single-particle and the particle-core components of the parent states, by comparing the best-fit resonance parameters with those given by model calculations. The internal consistency of this set was verified by using sum rules. The spectroscopic amplitudes are compared with those given by simple weak-coupling model predictions; there is considerable disagreement, probably because too few configurations were used in the theoretical calculations.
