Revision 50604 of "Interacting_boson_model" on enwiki

The '''Interacting Boson Model''' (IBM) is a model in [[nuclear physics]] in which
nucleons ([[proton]]s or [[neutron]]s) pair up, essentially
acting as a single [[particle]] with [[boson]] properties, with
integral [[spin (physics)|spin]] of 0, 2 or 4.

The [[IBM-I]] treats both types of [[nucleon]]s the same.

The [[IBM-II]] treats [[proton]]s and [[neutron]]s separately.
