Approximate analytic expression for B(E2) values in the interacting boson model

Abstract

A simple approximate analytic expression for calculating B(E2) transition amplitudes is derived in the framework of the interacting boson model. The expression gives values accurate within ±6% as compared to numerical calculations in either the phenomenological or the neutron-proton interacting boson model, and is valid for a large number of nuclei throughout the O(6)-SU(3) region.
