C14(α,γ) reaction rate Academic Article uri icon

abstract

  • The C14(α,γ) reaction rate at temperatures below 0.3 GK depends on the properties of two near threshold resonances in O18, the 1- at 6.198 MeV and the 3- at 6.404 MeV. The α+C14 asymptotic normalization coefficients for these resonances were determined using the α-transfer reactions C14(Li7, t) and C14(Li6, d) at sub-Coulomb energies. The C14(α,γ) reaction rate at low temperatures has been evaluated. Implications of the new reaction rate on the evolution of accreting helium white dwarfs and on the nucleosynthesis of low mass stars during the asymptotic giant branch phase are discussed. © 2009 The American Physical Society.
