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 either 2 (d-boson) or 0 (s-boson). They correspond to a quintuplet and singlet, i.e. 6 states.

It is sometimes known as the Interacting boson approximation (IBA).

History

This model was invented by Akito Arima and Francesco Iachello in 1974. while working at the Kernfysisch Versneller Instituut(KVI) in Groningen, Netherlands. KVI is now property of Universitair Medisch Centrum Groningen (https://umcgresearch.org/).
