Abstract

From the preceeding talks two different aspects of the interacting boson model (IBA) of collective degrees of freedom in nuclei have emerged. First the symmetry aspects of the model have been emphasized. It was shown that the Hamiltonian can be expressed in terms of the generators of the SU(6) group, and in special cases in terms of subgroups of SU(6); the application of group theoretical methods then provides an elegant and simple description of energy levels. Similarly the calculation of electromagnetic transition rates becomes straightforward. For example, it was shown that the one-boson E2 operator (neglecting separate neutronproton degrees of freedom)
$$ \hat T_\mu ^{\left( 2 \right)} = \alpha _2 \left( {s^ + d_\mu + d_\mu ^ + s} \right)^{\left( 2 \right)} + \beta _2 \left( {d^ + d} \right)_\mu ^{\left( 2 \right)} , $$

with constants α2 and β2 could describe experimental B(E2) values and quadrupole moments rather well.
