Description
Summary:Global fits to B(E2; 0 1 +→2 1 +) data using the fermion dynamical symmetry model (FSDM), the interacting boson model (IBM), and the Møller-Nix geometrical model (GM) are compared. The results indicate large dynamical Pauli effects leading to shell-dependent saturation of E2 strength consistent with the FDSM and GM, but not the IBM. The FDSM calculation is analytical with only a single adjustable parameter in each major shell, yet its accuracy rivals that of the best large-scale numerical calculations.
