Abstract
A new frontier of discrete-line -ray spectroscopy at ultrahigh spin has been opened in the rare-earth nuclei . Four rotational structures, displaying high moments of inertia, have been identified, which extend up to spin and bypass the band-terminating states in these nuclei which occur at . Cranked Nilsson-Strutinsky calculations suggest that these structures arise from well-deformed triaxial configurations that lie in a valley of favored shell energy which also includes the triaxial strongly deformed bands in .
