| Abstract: |
The 19 F(α, p)22 Ne reaction is considered to be the main source of fluorine depletion during the Asymptotic Giant Branch phase in stars. The reaction rate still retains large uncertainties due to the lack of experimental studies available. The yields for both the ground p0 and first excited state p1 exit channels of 22 Ne have been measured with the University of Notre Dame KN van de Graaff accelerator. Ten resonances were found in the energy range and their strengths have been determined. A comparison between the rate calculated from the experimental data and other standard rates is provided.
