dc.description.abstract | A systematic study of isotope chains in the rare-earth region is presented. For chains Nd-144-154(60),Sm-146-160(62),Gd-148-162(64), and Dy-150-166(66), energy levels, E2 transition rates, and two-neutron separation energies are described by using the most general (up to two-body terms) interacting boson model (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. | en_US |
