Abstract
The dynamic collective model and the dipole boson model are compared and the possibility of translating one into the other is investigated for deformed and SU(3) nuclei, respectively. It is shown that in one respect the two models are basically different. While it is natural in the dynamic collective model to have strong interactions between dipole and surface modes in deformed nuclei, the natural choice in the dipole boson model is that this coupling to the side bands is small for SU(3) nuclei. The latter is shown to be in agreement with the available experimental data. An analysis for 168Er shows that it is possible to obtain parameters for the dipole boson model from the hydrodynamic model which give a good account of all the experimental data. © 1987.
