Pairing at High Spin

TL;DR

This paper investigates pairing correlations in rotating nuclear systems using the HFB approximation, focusing on moments of inertia, rotational band classification, and transition signatures to unpaired states.

Contribution

It applies the HFB method to analyze pairing effects in high-spin states, providing insights into rotational behavior and phase transitions in nuclei.

Findings

Reduction of moments of inertia with increasing spin

Classification of rotational bands by quasiparticle configurations

Identification of transition signatures to unpaired states

Abstract

Pair correlations are described in the framework of the HFB approximation applied to a uniformly rotating system (Cranking model). The reduction of the moments of inertia, the classification of rotational bands as multi quasiparticle configurations, and the signatures of the rotation induced transition to the unpaired state are discussed.
