Abstract

The reaction rate of the stellar reaction [Formula presented], which is currently considered to be the main neutron source for the slow ([Formula presented]) process at low energies, has been rederived using the direct [Formula presented]-transfer reaction [Formula presented] leading to the subthreshold state at 6.356 MeV in [Formula presented]. The contribution of the subthreshold state is found to be much smaller than the currently accepted predictions for the main neutron source of the [Formula presented] process, indicating less of a role of this reaction as the neutron source for the [Formula presented]-process scenario in low-mass stars at the asymptotic giant branch.
