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

Abstract

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 (α, γ) 19 F was dominated by the contribution of three low-energy resonances, which enhanced the final 19 F abundance in the envelope.
