The finite-temperature Hartree-Fock-Bogoliubov cranking equation predicts the most probable shape for the /sup 158/Yb nuclei. At a spin-dependent critical temperature, there is a transition from prolate collective roatation to oblate noncollective rotation. For spins above 39(h/2..pi..), there is oblate noncollective rotation at all temperatures. However, inclusion of thermal shape fluctuations produces an average shape which is prolate collective at spins 40 and 50(h/2..pi..) and thermal excitation energy E/sup */approx. =10 MeV.
