New Results on Quantum Chaos in Atomic Nuclei
V. R. Manfredi, L. Salasnich
Abstract
In atomic nuclei, ordered and chaotic states generally coexist. In this paper the transition from ordered to chaotic states will be discussed in the framework of roto-vibrational and shell models. In particular for 160Gd, in the roto-vibrational model, the Poincarè sections clearly show the transition from order to chaos for different values of rotational frequency. Furthermore, the spectral statistics of low-lying states of several fp shell nuclei are studied with realistic shell-model calculations.
