    "abstract": "Spectrum generating algebras are used in various fields of physics as models\nto determine quantum structure, including energy levels and transition\nstrengths. The advantage of such models is that their group structure allows an\nextensive understanding of the system being studied. In addition they possess a\nsimple classical limit, at least for bosonic systems. In this paper we discuss\nan algebraic model of nuclear structure, the Interacting Boson Model (IBM), and\nshow that in one limit its group structure is particularly simple. For zero\nangular momentum there is an effective lower dimensional group structure which\ndescribes the system both classically and quantum mechanically.",
