What are the limits of nuclear existence? How do the limits of weak binding
and extreme proton-to-neutron asymmetries affect nuclear properties?
These are two of the key questions in current nuclear physics.
Now that we have the first of new-generation RI-Beam facilities,
the RI Beam Factory (RIBF) at RIKEN, we have started exploring towards the
limits of nuclear existence on the heavier, and more neutron-rich side.
In this seminar, after introducing this new facility, I will present
results on breakup experiments and revealed structures
on weakly bound drip-line nuclei in B,C,Ne,Mg, and Si isotopes
at the relativistic energies of RIBF. The main focus is put also
on how we can investigate exotic structures, such as halo structure,
by Coulomb breakup with a heavy target
and nuclear breakup with a light target.  We have indeed found some new
cases of halo structures . Implications of these findings and near future plans at
RIBF will also be discussed.
