[en] Excitation functions for proton elastic scattering and for proton induced reactions were measured with the KN Van de Graaff and associated high resolution system at TUNL for two odd-mass targets. Excitation functions for ²⁹Si(p,p), (p,p₁), and (p,p₂) were obtained in the range E/sub p/ = 1.29 to 3.30 MeV, and the ²⁷Al(p,p), (p,p₁), (p,p₂), (p,α₀), and (pα₁) differential cross sections were measured at four angles with an overall resolution that varied between 350 - 450 eV, full width at half maximum. The measured excitation functions were analyzed with a multi-level, multi-channel R-matrix formalism. The parameters extracted from the data include the resonance energy, total angular momentum, partial elastic and reaction widths, and channel spin and orbital angular momentum mixing ratios. Resonance parameters were determined for 66 resonances in ³⁰P in the range E/sub x/ = 6.85 to 8.79 MeV, and for 104 resonances in ²⁸Si in the range E/sub x/ = 12.47 to 14.53 MeV. The dependence of the resonance shapes on the channel spin mixing ratio and on the I-mixing ratio was investigated for proton scattering. Seven isobaric analog states were identified in ³⁰P and eighteen analog states were identified in ²⁸Si. Coulomb energies and proton spectroscopic factors were determined and the analog strengths compared with the parent state (d,p) spectroscopic factors
