Phys. Rev. Lett. 85, 2693–2696 (2000)Superdeformation in the N = Z Nucleus 36Ar: Experimental, Deformed Mean Field, and Spherical Shell Model DescriptionsReceived 8 May 2000; published in the issue dated 25 September 2000 A superdeformed rotational band has been identified in 36Ar, linked to known low-spin states, and observed to its high-spin termination at Iπ = 16+. Cranked Nilsson-Strutinsky and spherical shell model calculations assign the band to a configuration in which four pf-shell orbitals are occupied, leading to a low-spin deformation β2≈0.45. Two major shells are active for both protons and neutrons, yet the valence space remains small enough to be confronted with the shell model. This band thus provides an ideal case to study the microscopic structure of collective rotational motion. © 2000 The American Physical Society URL:
