High spin structures in the A ≈ 40 mass region: from superdeformation to extreme deformation and clusterization (an example of 28Si)

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