Superdeformed (SD) bands have been identified in both the A \approx 150 and A \approx 60 regions using the statistical thoery and the configuration dependent cranked Nilsson–Strutinsky (CNS) calculations. A good understanding of SD bands in different mass regions have been obtained using these models and the general features of SD bands in these mass regions are studied. Total energy surfaces (TES) have also been generated for these nuclei with in the CNS formalism to study the shape transition and oblate –- prolate coexistence in detail.
