Asymptotic normalization coefficients in nuclear astrophysics and structure

Abstract

The asymptotic normalization coefficient (ANC) for a nuclear system specifies the normalization of the tail of the nuclear overlap function. ANCs may be determined experimentally by measuring peripheral nuclear reactions. They may be used to calculate the astrophysical S-factors for radiative capture reactions at stellar energies and to determine the halo structure of loosely bound nuclei. A brief introduction to ANCs is given and applications to the 7Be(p, γ)8B and 11C(p, γ)12N reactions and the halo structure of 8B are described.
