Asymptotic normalization coefficient for the 12C→11C+n from 12C(p,d)11C and 12C(3He,α)11C neutron transfer reactions

The neutron transfer reactions [Formula: see text] at a proton incident energy of 52[Formula: see text]MeV and [Formula: see text] at a 3 He incident energy of 36[Formula: see text]MeV have been investigated within the framework of the modified distorted wave born approximation. The reactions were analyzed to examine their peripheral nature and to extract the experimental asymptotic normalization coefficient (ANC) for the virtual decay [Formula: see text]. The values of the ANC extracted independently from the [Formula: see text] and [Formula: see text] reactions were compared and found to be in good agreement within the uncertainties. Based on the results of the two independent transfer reactions, the recommended ANC for the [Formula: see text] configuration was determined to be [Formula: see text]. This result provides reliable information on the overlap between the [Formula: see text]C and [Formula: see text] nuclear wave functions and constitutes an important nuclear-structure quantity for indirect investigations of reactions involving the [Formula: see text]C nucleus, particularly those relevant to nuclear astrophysics.
