Improved Exponential model with pairing attenuation and the backbending phenomenon

Abstract

A modified version of the exponential model with paring attenuation is proposed, and used to describe successfully the backbending of the moment of inertia, in even-even nuclei, not only in well-deformed nuclei but also in slightly deformed nuclei. The model remarkably fits good the experimental observation with a few parameters.
