Abstract

A highly-deformed rotational band has been identified in the N = Z nucleus ³⁶Ar. At high spin the band is observed to its presumed termination at I^π = 16⁺, while at low spin it has been firmly linked to previously known states in ³⁶Ar. Spins, parities, and absolute excitation energies have thus been determined throughout the band. Lifetime measurements establish a large low-spin quadrupole deformation (β₂ = 0.46 ±0.03) and indicate a decreasing collectivity as the band termination is approached. With effectively complete spectroscopic information and a valence space large enough for significant collectivity to develop, yet small enough to be meaningfully approached from the shell model perspective, this rotational band in ³⁶Ar provides many exciting opportunities to test and compare complementary models of collective motion in nuclei.
