Correlated Nucleon Pair Model and Microscopic Basis of Interacting Boson

Abstract

An earlier work dealing with low-lying collective states in nuclei is revised and improved. Correlated and independent nucleon and pairs properly modified so that they behave approximately like bosons are constructed in terms of which a model space for low-lying collective states is defined, and a microscopic basis for IBM is thus set up. All dynamical variables can also be “bosonized”, i.e., expressed in terms of these “bosons” but with state-dependent coefficients or operators to incorporate their state dependence in model space.
