    "abstract": "A general study of excitations up to two-phonon states is carried out using\nthe intrinsic-state formalism of the Interacting Boson Model (IBM). Spectra and\ntransitions for the different dynamical symmetries are analyzed and the\ncorrespondence with states in the laboratory frame is established. The\ninfluence of multi-phonon states is discussed. The approach is useful in\nproblems where the complexity of the IBM spectrum renders the analysis in the\nlaboratory frame difficult.",
