    "abstract": "Double-$\\gamma$ vibrations in deformed nuclei are studied in the context of\nthe interacting boson model with special reference to their anharmonic\ncharacter. It is shown that large anharmonicities can be obtained with\ninteractions that are (at least) of three-body nature between the bosons. As an\nexample the $\\gamma$ vibrations of the nucleus\n$^{166}_{\\phantom{0}68}$Er$^{\\phantom{00}}_{98}$ are studied in detail.",
