    "abstract": "A Deformed Gaussian Orthogonal Ensemble (DGOE) which interpolates between the\nGaussian Orthogonal Ensemble and a Poissonian Ensemble is constructed. This new\nensemble is then applied to the analysis of the chaotic properties of the low\nlying collective states of nuclei described by the Interacting Boson Model\n(IBM). This model undergoes a transition order-chaos-order from the $SU(3)$\nlimit to the $O(6)$ limit. Our analysis shows that the quantum fluctuations of\nthe IBM Hamiltonian, both of the spectrum and the eigenvectors, follow the\nexpected behaviour predicted by the DGOE when one goes from one limit to the\nother.",
