摘要：

A recent study of the onset of chaos in the low-lying collective states of nuclei, which uses the interacting boson model, is extended to higher spins and/or higher energies by including broken pairs. Spectral fluctuations are studied as a function of the quadrupole-quadrupole interaction between the fermion pair and the core and the pair-breaking interaction that mixes states with different number of fermions. The effects of the Coriolis force are discussed.
