Matrix Elements of Random Operators and Discrete Symmetry Breaking in Nuclei
arXiv:nucl-th/0203021 · doi:10.1103/PhysRevLett.84.3783
Abstract
It is shown that several effects are responsible for deviations of the intensity distributions from the Porter-Thomas law. Among these are genuine symmetry breaking, such as isospin; the nature of the transition operator; truncation of the Hilbert space in shell model calculations and missing transitions
