Abstract

The astrophysically important reaction ¹⁴O(α,p)¹⁷F has been studied through a measurement of the time-inverse p(¹⁷F,α)¹⁴O reaction using a radioactive ¹⁷F beam. Resonance parameters for several states above an excitation energy of 7 MeV in ¹⁸Ne have been obtained. Through a measurement of the partial widths for elastic and inelastic proton scattering, it was determined that for these resonances the contribution of the ¹⁴O(α,p)¹⁷F* branch populating the first excited state in ¹⁷F is small. The results indicate that the contribution of resonances above E_x=7 MeV to the astrophysical (α,p) reaction rate is smaller than was previously assumed.
