Abstract: An excitation function of the 19F(p, αγ)16O reaction has been measured over the proton beam energy range Ep= 200–800 keV using a 4 π NaI summing spectrometer. A new resonance was found at ER= 237 keV and its properties ΓR, σR and ωγ have been extracted. The strengths of all resonances at Ep= 200–800 keV have been also extracted. The importance of the 1+ resonance at ER= 11 keV is discussed and its width has been estimated taking into account interference effects with the strong 1+ resonance at ER= 340 keV. The reaction rates have been calculated over a wide range of temperatures and compared with the rates of the (p, α0) and (p, απ) branches of the 19F(p, α)16O reaction.
