66Dy, energy levels, E2 transition rates, and two–
neutron separation energies are described by using the most general (up to two–body terms) IBM
Hamiltonian. For each isotope chain a general fit is performed in such a way that all parameters
but one are kept fixed to describe the whole chain. In this region nuclei evolve from spherical to
deformed shapes and a method based on catastrophe theory, in combination with a coherent state
analysis to generate the IBM energy surfaces, is used to identify critical phase transition points.},
