Query: Neutron-induced nucleosynthesis   Neutron--induced nucleosynthesis plays an important role in astrophysical
scenarios like in primordial nucleosynthesis in the early universe, in the
s--process occurring in Red Giants, and in the $\alpha$--rich freeze--out and
r--process taking place in supernovae of type II. A review of the three
important aspects of neutron--induced nucleosynthesis is given: astrophysical
background, experimental methods and theoretical models for determining
reaction cross sections and reaction rates at thermonuclear energies. Three
specific examples of neutron capture at thermal and thermonuclear energies are
discussed in some detail.
