    "abstract": "The anharmonic vibrator and rotor regions in nuclei are investigated in the\nframework of the interacting boson model using an ensemble of random one- and\ntwo-body interactions. We find a predominance of L(P)=0(+) ground states, as\nwell as strong evidence for the occurrence of both vibrational and rotational\nband structures. This remarkable result suggests that such band structures\nrepresent a far more general (robust) property of the collective model space\nthan is generally thought.",
