Abstract

A superdeformed rotational band has been identified in the N = Z nucleus ³⁶Ar, firmly linked to known low-spin states, and observed to its high-spin termination at I^π = 16⁺. Lifetime measurements by the Doppler shift attenuation method establish a large low-spin deformation (β₂ ≈ 0.46) and a decrease in the collectivity as the band approaches termination. Comparisons with cranked Nilsson-Strutinsky and large-scale spherical shell model calculations lead to a consistent description of the band based on a configuration in which four particles are promoted to the pf shell. With two major shells active for both protons and neutrons, yet a valence space dimension small enough to be approached from the shell model perspective, this band offers an excellent opportunity to investigate the microscopic structure of collective rotational motion in nuclei.
