Polarized proton capture on Si30

Journal Article

The 90°yield curves for the Si30(p, 0)P31 and Si30(p, 1)P31 reactions have been measured for Ep=5.0 to 28.0 MeV. Angular distributions of cross section and analyzing power were obtained at twelve energies between Ep=6.36 and 14.45 MeV. The cross sections were measured at nine angles between 30°and 154°, the analyzing power at seven angles between 42°and 142°. For the case of (p, 0) the complex T-matrix elements were extracted, assuming that the angular distributions are governed by coherent E1 and E2 processes. Two (E2) yield curves are obtained, one of which exhausts 9-12% of the 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.
