The Nucleosynthesis and Reaction Rates of Fluorine 19 (${}^{19}F$) in the Sun

Abstract

We investigate the abundance of ${}^{19}F$ in the Sun through the nucleosynthesis scenario. In addition, we calculate the rate equations and reaction rates of the nucleosynthesis of ${}^{19}F$ at different temperature scale. Other important functions of this nucleosynthesis (nuclear partition function and statistical equilibrium conditions) are also obtained. The resulting stability of ${}^{19}F$ 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 ${}^{19}F$ is produced. The reaction rate of ${}^{15}N$ ($\alpha$, $\gamma$) ${}^{19}F$ was dominated by the contribution of three low-energy resonances, which enhanced the final ${}^{19}F$ abundance in the envelope.
