[en] Excitation functions have been measured for elastic scattering of polarized protons from ₂₀₆Pb and ₂₀₈Pb, and for inelastic scattering to collective states in ₂₀₆Pb (2⁺, 0.8033 MeV; 3^-, 2.647 MeV) and ₂₀₈Pb (3^-, 2.6145 MeV). Both differential cross sections and analyzing powers were measured at theta_lab = 120₀, 135₀, 150₀, and 165₀, for E_p = 14.25 to 18 MeV. Fits to the excitation-function data were obtained using scattering amplitudes consisting of sums of resonant and non-resonant parts. The resonances are the isobaric analogs (IARs) of 7 low-lying states in ₂₀₉Pb and 35 in ₂₀₇Pb. The fits to the elastic-scattering data are excellent; for the inelastic scattering the fit is very good for the 2⁺ state but only fair for the 3^- states. For each IAR, the energy, the total width, and the partial width and mixing phase in each channel were obtained. Also, new spin assignments were made for a number of parent states in ₂₀₇Pb. The theory of Bund and Blair was used to find the spectroscopic amplitudes, which provide information on the wave functions for the parent states in ₂₀₇Pb and ₂₀₉Pb and for the 3^- states in ₂₀₆Pb and ₂₀₈Pb. These spectroscopic amplitudes were then checked for internal consistency and compared with the results of other experiments and with theoretical predictions
