The interacting boson model, also known as the IBM, is a theoretical framework in nuclear physics that describes the collective behavior of atomic nuclei. It is based on the concept of bosons, particles that follow a different set of rules than fermions. While there are no direct synonyms for the term "interacting boson model," there are related terms used in the field of nuclear physics. For example, there is the concept of a "collective model," which is a term that is used to describe the behavior of atomic nuclei that have a large number of nucleons. Additionally, the "nuclear shell model" is another theoretical framework that describes the structure of atomic nuclei.
