Abstract

The Interacting Boson Model (IBM) can be extended to the description of collective bands built on two-, or four-quasiparticle states, if the model Hamiltonian allows for the change of one, or two bosons into quasiparticle pairs. An IBM version including up to two broken pairs is here applied to transitional nuclei with neutron number N = 74, with emphasis on negative-parity dipole bands, for which preliminary results on electromagnetic transition strengths are also presented
