Sammanfattning

Lifetimes have been measured in a superdeformed rotational band recently identified in the N = Z nucleus ³⁶Ar. A large low-spin quadrupole deformation (β₂=0.46±0.03) is confirmed and a decrease in the collectivity is observed as the high-spin band termination at I^π=16⁺ is approached. Detailed comparisons of the experimental B(E2) values with the results of cranked Nilsson-Strutinsky and large-scale (s_1/2d_3/2)-pf spherical shell model calculations indicate the need for a more refined treatment of transition matrix elements close to termination in the former, and the inclusion of the complete sd-pf model space in the latter description of this highly-collective rotational band.
