Interacting Boson Model
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.
The IBM-I treats both types of nucleons the same and considers only pairs of nucleons coupled to total angular momentum 0 and 2, called respectively, s and d bosons. The IBM-II treats protons and neutrons separately.

Famous quotes containing the word model:
“...that absolutely everything beloved and cherished of the bourgeoisie, the conservative, the cowardly, and the impotentthe State, family life, secular art and sciencewas consciously or unconsciously hostile to the religious idea, to the Church, whose innate tendency and permanent aim was the dissolution of all existing worldly orders, and the reconstitution of society after the model of the ideal, the communistic City of God.”
—Thomas Mann (18751955)
