The interacting boson model
A. Arima,Francesco Iachello +1 more
TL;DR: In this article, the authors examine the algebraic and geometric properties of the interacting boson model-1 and review the interaction model-2, and discuss analytic solutions, transitional classes, extensions of the models, coherent states, transition classes and shape phase transitions, energy levels, electromagnetic transition rates, other properties, a microscopic description of interacting bosons, generalized seniority, the single j-shell, several jshells, and the Ginocchio model.

The Interacting Boson Model
H Feshbach,Francesco Iachello +1 more
TL;DR: In this paper, the authors proposed a geometrical description of the shell structure of the nucleus with major closed shells at nucleon number 50, 82, 126, and 126.

Boson realizations of Lie algebras with applications to nuclear physics
TL;DR: The concept of boson realization (or mapping) of Lie algebras appeared first in nuclear physics in 1962 as the idea of expanding bilinear forms in fermion creation and annihilation operators in Taylor series of Boson operators, with the object of converting the study of nuclear vibrational motion into a problem of coupled oscillators.

Shell-model foundations of the interacting boson model
Francesco Iachello,Igal Talmi +1 more
TL;DR: In this article, the authors discuss the concepts on which the interacting boson model is based, in particular those of pairing and seniority, which lead to a connection with the shell model.
Journal ArticleDOI
The interacting boson model of nuclear structure
TL;DR: In this paper, the authors present a review of the interacting boson model in its different forms and a discussion of its applications to a range of nuclei, including a survey of the more firmly established nuclear models.

Field dependence of the intrinsic domain magnetization of a ferromagnet
T. Holstein,H. Primakoff +1 more
TL;DR: In this article, the intrinsic domain magnetization of a ferromagnetic with the external magnetic field was obtained, and an approximation to low temperatures and equivalent to those used by Bloch in his derivation of the ${T}^{1}$ law, were introduced.

Nuclear Shell Model and Interacting Bosons
TL;DR: In this paper, the interacting boson model provides us with a unified phenomenological description of vibrational, rotational and transitional nuclei, and it has been shown that the model can provide a unified description of nuclei.

Anharmonic effects of quadrupole oscillations of spherical nuclei
S.T. Beliaev,Vladimir Zelevinsky +1 more
TL;DR: In this paper, the authors considered deviations from the principal "harmonic" approximation in the framework of the microscopic theory of the collective excitations of spherical even nuclei and derived the corrections to the wave functions, energy levels and the E2 transition probabilities for the first two excited states.

On the “Anharmonic Effects” on the Collective Oscillations in Spherical Even Nuclei. I
TL;DR: In this paper, a new method which enables us to transcribe the dynamics of the system of even nuclei into that of the boson system is developed, with the purpose of analysing the " anharmonic effects " on the collective oscillations in spherical Even nuclei from the standpoint of the microscopic theory of the collective excitations.

Study of boson expansion methods in an exactly soluble two-level shell model
TL;DR: In this article, a two-level numerically soluble shell model was used to investigate the accuracy of the random phase and related approximations for the description of a vibrational spectrum, since the model is expressed completely in terms of quasi-spin operators, the required correspondence to boson operators is given by well known results from the theory of ferromagnetism.
