High spin structures in the $A\approx 40$ mass region: from superdeformation to extreme deformation and clusterization (an example of $^{28}$Si)

TL;DR

This paper investigates highly deformed nuclear structures in $^{28}$Si using cranked relativistic mean field theory, revealing clear signs of clusterization in superdeformed and hyperdeformed states up to high angular momentum.

Contribution

It applies cranked relativistic mean field theory to identify and analyze superdeformed and hyperdeformed configurations in $^{28}$Si, highlighting clusterization effects.

Findings

Pronounced clusterization in superdeformed states

Identification of hyperdeformed configurations

Deformation effects observed up to spin $I=20\hbar$

Abstract

The search for extremely deformed structures in the yrast and near-yrast region of $^{28}$Si has been performed within the cranked relativistic mean field theory up to spin $I=20\hbar$. The fingerprints of clusterization are seen (well pronounced) in the superdeformed (hyperdeformed) configurations.
