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(
)
8B and
11C(
)
12N reactions
and the halo structure of
8B are described.
