  We present nuclear physics programs based on the planned experiments using
rare isotope beams (RIBs) for the future Korean Rare Isotope Beams Accelerator
facility; RAON. This ambitious facility has both an Isotope Separation On Line
(ISOL) and fragmentation capability for producing RIBs and accelerating beams
of wide range mass of nuclides with energies of a few to hundreds MeV per
nucleon. Low energy RIBs at Elab = 5 to 20 MeV per nucleon are for the study of
nuclear structure and nuclear astrophysics toward and beyond the drip lines
while higher energy RIBs produced by in-flight fragmentation with the
re-accelerated ions from the ISOL enable to explore the neutron drip lines in
intermediate mass regions. The planned programs have goals for investigating
nuclear structures of the exotic nuclei toward and beyond the nucleon drip
lines by addressing the following issues: how the shell structure evolves in
areas of extreme proton to neutron imbalance; whether the isospin symmetry
maintains in isobaric mirror nuclei at and beyond the drip lines, how
two-proton radioactivity affects abundances of the elements, what the role of
the continuum states including resonant states above the neutron- and
proton-decay threshold in exotic nuclei is in astrophysical nuclear reaction
processes, and how the nuclear reaction rates triggered by unbound proton-rich
nuclei make an effect on rapid proton capture processes in a very hot stellar
plasma.
