  The present communication is a continuation of the review, the first part of
which was presented in nucl-th/0109033. The second part dealswith the
manifistation of Chaotic dynamics at quantum level. The variations of
statistical properties of energy spectrum in the process of R-C-R transition
have been studied in detail. We proved that the type of the classical motion is
correlated with the structure of the eigenfunctions of highly excited states in
the R-C-R transition. Shell structure destruction induced by the increase of
nonintegrable perturbation was analyzed.
