The quantum behavior and structural properties of exotic nuclei i.e.
nuclei far from the 
-stability line, can be viewed as one of the
most actual directions of research in contemporary nuclear physics.
There exist numerous experimental projects under construction that will
soon produce new output. Several theoretical methods, although so far
quite successful in various applications, must be re-examined. This concerns
in particular the more adequate parametrisations of nuclear interactions
as well as "practical" realizations of the implied approximations and methods
(Hartree-Fock, Macroscopic-Microscopic method of Strutinsky, the Shell Model
and probably others).
