Abstract
Present days' nuclear physics has focused on exploring fundamental nuclear
matter under extreme conditions, which can be created in modern accelerator
laboratories. The opportunities offered by beams of exotic nuclei for a
research in the areas of nuclear-structure physics, nucleosynthesis and
nuclear astrophysics are exciting, and the large worldwide activity in the
construction of radioactive-beam facilities reflects the strong scientific
interest in the physics that can be probed with such beams.
On the neutron-rich side of stability radioactive beams have already led to
the discovery of halos in nuclei with nucleonic distributions extending
to large
distances. Light nuclei constitute so far the part of the nuclear landscape
where the neutron dripline has been reached. Subsequent developments have
deepened and enriched the
picture of halos as a pure quantum mechanics phenomenon, where particles can be
found far from each other in classically forbidden regions.
Few-body dynamics plays a crucial role in every adequate description of
the discovered halo properties and just few-body methods lead at the early
stage to self-consistent explanations of most of the experimental
findings in halo physics.
We discuss experiments that probe a halo structure through studying different
reactions with halo nuclei.
We discuss also theoretical methods and models based on few-body
approaches, which allow to extract an accurate spectroscopic information
from experiments and make predictions for future experiments.
