Abstract
We study classically and quantum mechanically the chaotic properties o f low-lying collective states of nuclei by using the interacting boson model. Classical and quantal diagrams am constructed for several meas ures of chaos in a general parameter space of the hamiltonian known as Casten's triangle. Strong correlations are found between the classica l and quantal results. A new nearly regular region is discovered.
