A Study of the $^{14}$C(?,?) Reaction Rate Through the ANC Technique

ORAL

Abstract

The astrophysical significance of the $^{14}$C(?,?) reaction is due to its involvement in the NCO chain. The NCO chain is thought to trigger He flashes in white dwarf stars, and is also thought to be a neutron source for the s-process in low mass stars [L. Buchmann et al., The Astrophys. Journ. 324 (1988), M. Hashimoto et al., The Astrophys. Journ. 307 (1986)]. Recently the ANC of the 3$^{-}$, 6.4 MeV, near threshold state in $^{18}$O was measured via a sub-Coulomb, inverse kinematics ?-transfer reaction at the Florida State University J.D. Fox Superconducting Accelerator Laboratory. The $^{14}$C(?,?) reaction rate at stellar temperatures is highly dependent upon the structure of this 3$^{-}$ state. As shown in E.D. Johnson et al. PRL 97 (2006) the measured ANC can be used to calculate the $^{14}$C(?,?) reaction rate without any dependence on nuclear models.
