The 90/sup 0/ yield curves for the /sup 30/Si( p,..gamma../sub 0/)/sup 31/P and /sup 30/Si( p,..gamma../sub 1/)/sup 31/P reactions have been measured for E/sub p/=5.0 to 28.0 MeV. Angular distributions of cross section and analyzing power were obtained at twelve energies between E/sub p/=6.36 and 14.45 MeV. The cross sections were measured at nine angles between 30/sup 0/ and 154/sup 0/, the analyzing power at seven angles between 42/sup 0/ and 142/sup 0/. For the case of ( p,..gamma../sub 0/) the complex T-matrix elements were extracted, assuming that the angular distributions are governed by coherent E1 and E2 processes. Two sigma(E2) yield curves are obtained, one of which exhausts 9--12% of the ..delta..T=0 E2 energy weighted sum rule while the other exhausts 21--31%. The results are compared to direct-semidirect model calculations which suggest that the larger E2 cross sections are the physical solutions.
