Abstract
I discuss first
the effect of decoupling of extended wave functions and
the coherence in
the low-energy
E1 strength in drip line nuclei
12Be and
13O,
which are studied
by large-scale shell model calculations including 3
configuration space. The calculated results are compared to
recent experimental data of Coulomb excitations.
The quenching of the core polarization
charges in drip line nuclei
is also discussed in relation to recent observations
of quadrupole moments in B-isotopes.
