Abstract

The astrophysical rate of the ¹⁸F(p,α)¹⁵O reaction at nova temperatures is critical to understanding production of the radioisotope ¹⁸F, which may be used to constrain nova models via observations with the coming generation of satellite-based γ-ray telescopes. As such, a measurement is made of the strength of this resonance using a radioactive ¹⁸F beam at the HRIBF. As a result, it is indicated that the ¹⁸F(p,α)¹⁵O reaction rate is lower than previous estimates by a factor of ∼2.
