The interacting boson model was introduced in as an attempt to describe collective properties of nuclei in a unified way.

Sincethe model has been the subject of many investigations and it has been extended to cover most aspects of nuclear structure. This book gives an account of the properties of the interacting boson by: This text is designed to provide physicists with an accessible introduction to the interacting boson model, an approach to nuclear structure that was first proposed inwith several important extensions and generalizations appearing over the last decade.

The value of this model lies in the fact that the traditional shell model of nuclear structure is limited in its application to light. An introduction to the algebraic description of nuclear collective motion in terms of the Interacting Boson Model (IBM) and its various extensions.

This model allows for detailed calculations of the properties of even, medium and heavy nuclei which cannot be reached by the shell model yet. The interacting boson model was introduced in as an attempt to describe collective properties of nuclei in a unified way.

number of nuclear states soon becomes so colossal that the shell model will be intractable. For example the 2+ state (spin 2 and positive parity) of Sm shows 3⋅ different configurations (Casten,p.

The interacting boson model (sometimes named interacting boson approximation IBA) reduces the number of states heavily. Interacting boson models provide an elegant and powerful method to describe collective excitations of complex systems by introducing a set of effective degrees of freedom. We review the interacting boson model of nuclear structure and discuss a recent extension to the nucleon and its excited states.

The interacting boson model. •Nuclear collective excitations are described in terms of N s and d bosons. •Spectrum generating algebra for the nucleus is U(6). All physical observables (hamiltonian, transition operators,) are expressed in terms of the generators of U(6).

We note that in the interacting boson model-1 (IBM-1) [1,2] one describes an even-even nucleus as a system of N bosons able to occupy two levels, one with angular momentum re-stricted to zero (s boson) and one with angular momentum 2 (d boson).

The bosons are assumed to interact via a two-body resid-ual interaction. Recent theoretical developments in using the interacting boson model to describe nuclear structure effects in fusion reactions below the Coulomb barrier are reviewed. Methods dealing with linear and all-order coupling between the nuclear excitations and the translational motion are discussed, and the latter is found to lead to a better description of the barrier distribution by: 4.I'm reading about the interacting boson model in both Wong's Introductory Nuclear Physics () and Casten's Nuclear structure from a simple perspective ().
