Vr. Manfredi et L. Salasnich, THE ONSET OF CHAOS WITH A QUADRUPOLE-QUADRUPOLE INTERACTION, Nuovo cimento della Società Italiana di Fisica. A. Nuclei, particles and fields, 108(4), 1995, pp. 449-458
The transition from order to chaos in atomic nuclei has been studied a
nalytically and numerically using a quadrupole-quadrupole residual int
eraction. This interaction leads to chaotic behaviour, but the critica
l energy E(C) similar or equal to 12.6 MeV, corresponding to the onset
of chaos, is higher than that of the experimental one.
