摘要：

An excitation function for the F-18(p,alpha)O-15 reaction has been measured in the energy range E(c.m.)=600-800 keV using a radioactive F-18 beam. A resonant state with a spin value of 3/2(+) has been found at an energy of 652 keV above threshold. This l(p)=0 resonance is found to dominate the astrophysical reaction rate at temperatures T-9>0.5.
