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

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 $I=20\hslash$. The fingerprints of clusterization are seen (well pronounced) in the superdeformed (hyperdeformed) configurations.
