Abstract
Nucleons with very small binding energies present in nuclei far from the
stability line produce a unique shell structure, which leads to the disappearance
of traditional magic numbers or to the creation of new magic numbers and new
deformation regions. We study the shell structure in terms of the variation
of two important ingredients, the kinetic energy and the spin-orbit
splitting, as a function of the orbital angular momentum
,
when binding energies of neutrons decrease towards zero.
It is also shown that for low-lying threshold strength,
a negative sign is possible for the polarization charge coming from
the coupling of
one-particle to isoscalar shape
oscillations.
