Vr. Manfredi et L. Salasnich, ORDER AND CHAOS IN ROTO-VIBRATIONAL STATES OF ATOMIC-NUCLEI, International journal of modern physics E, 4(3), 1995, pp. 625-636
Using a classical analytical criterion (that of curvature) and numeric
al results (Poincare sections and spectral statistics), a transition o
rder-chaos-order in the roto-vibrational model of atomic nuclei has be
en shown. Numerical calculations were performed for some deformed nucl
ei.
