Hyperdeformation in the cranked relativistic mean field theory: the Z=40-58 part of nuclear chart

TL;DR

This paper systematically investigates hyperdeformation phenomena at high spin states in nuclei with atomic numbers 40 to 58 using cranked relativistic mean field theory, focusing on moments of inertia, single-particle effects, and observability.

Contribution

It provides a comprehensive analysis of hyperdeformation in the specified nuclear region within the relativistic mean field framework, highlighting new insights into high-spin behavior.

Findings

Hyperdeformed bands exhibit characteristic moments of inertia.

Single-particle and necking effects significantly influence hyperdeformation.

Certain hyperdeformed states become yrast at specific spins.

Abstract

The systematic investigation of hyperdeformation (HD) at high spin in the $Z=40-58$ part of the nuclear chart has been performed in the framework of the cranked relativistic mean field theory. The properties of the moments of inertia of the HD bands, the role of the single-particle and necking degrees of freedom at HD, the spins at which the HD bands become yrast, the possibility to observe discrete HD bands etc. are discussed in detail.
