Proton elastic scattering on {sup 28}Si was measured with good beam energy resolution in the proton energy range E{sub p} {equals} 1.4 to E{sub p} {equals} 3.75 MeV, and proton inelastic scattering on {sup 28}Si was studied from E{sub p} {equals} 3.0 to 3.75 MeV. A resonance not previously seen in the elastic scattering channel was observed at E{sub p} {equals} 2.287 MeV; the elastic width was measured to be 80 eV. The resonance at E{sub p} {equals} 3.102 MeV had been assigned J{sup {pi}} {equals} 5/2{sup {minus}} from previous proton elastic and inelastic scattering data. From the present measurements the spin and parity of the resonance is J{sup {pi}} {equals} 7/2{sup {minus}}. The capture yields were used to locate extremely weak resonances near E{sub p} {equals} 1.377 MeV and 2.630 MeV. Upper limits for the elastic widths of the resonances at E{sub p} {equals} 1.377 MeV and 2.630 MeV are 2 eV; this reduced the previous upper limits for the elastic widths by 3 orders of magnitude. The resonance at E{sub p} {equals} 2.630 MeV has an inelastic width of 10 eV. Spectroscopic factors for the resonances in {sup 29}P were compared with those for the levels in the parent nucleus {sup 29} Si. Large Thomas-Ehrman shifts are observed for a number of the mirror levels.
