Abstract
Double-gamma vibrations in deformed nuclei are studied in the context of th e interacting boson model with special reference to their anharmonic charac ter. It is shown that large anharmonicities can be obtained with interactio ns that are (at least) of three-body nature between the bosons. As an examp le the gamma vibrations of the nucleus Er-166(68)98 are studied in detail.
