The Nucleosynthesis and Reaction Rates of Fluorine 19 (19F) in the Sun

Abstract

We investigate the abundance of 19F in the Sun through the nucleosynthesis scenario. In addition, we calculate the rate equations and reaction rates of the nucleosynthesis of 19F at different temperature scale. Other important functions of this nucleosynthesis (nuclear partition function and statistical equilibrium conditions) are also obtained. The resulting stability of 19F occurs at nucleus with A = 19 and Mass Excess = -1.4874 MeV. As a result, this will tend to a series of neutron captures and beta-decay until 19F is produced. The reaction rate of 15N (α, γ) 19F was dominated by the contribution of three low-energy resonances, which enhanced the final 19F abundance in the envelope.
