The interacting boson model (IBM) is a model in nuclear physics in which nucleons (protons or neutrons) pair up, essentially acting as a single particle with boson properties, with integral spin of 0, 2 or 4.
It is sometimes known as the Interacting boson approximation (IBA).:7
Both models are restricted to nuclei with even numbers of protons and neutrons.:9
The model can be used to predict vibrational and rotational modes of non-spherical nuclei.
