Abstract

The interference effects among Jπ=3/2+ resonances in the F18+p system have not been previously measured. R-matrix calculations show that the cross sections above the Ec.m.=665 keV resonance are sensitive to the interference between the Ec.m.=8, 38, and 665 keV resonances. An excitation function for the H1(F18,α)O15 reaction has been measured in the energy range of Ec.m.=663-877 keV using radioactive F18 beams at the Holifield Radioactive Ion Beam Facility (HRIBF). By comparing the observed cross sections with the R-matrix calculations, we provide the first experimental constraints on the interference. Upper limits on proton widths (Γp) of the Ec.m.=827 and 842 keV resonances have been set as well. © 2006 The American Physical Society.
