Abstract

Double-$��$ vibrations in deformed nuclei are analyzed in the context of the interacting boson model. A simple extension of the original version of the model towards higher-order interactions is required to explain the observed anharmonicities of nuclear vibrations. The influence of three- and four-body interactions on the moments of inertia of ground- and $��$-bands, and on the relative position of single-$��$ and double-$��$ bands is studied in detail. As an example of a realistic calculation, spectra and transitions of the highly $��$-anharmonic nuclei $^{164}$Dy, $^{166}$Er, and $^{168}$Er are interpreted in this approach.
