Abstract

Three rotational bands have been discovered in the nucleus Sb109 that extend in angular momentum to 81/2Latin small letter h with stroke. The rotational frequency at the highest spins reaches Latin small letter h with strokeω1.4 MeV, the highest frequency so far observed in a heavy nucleus. With increasing frequency the collective moments of inertia of all three bands smoothly diminish to unexpectedly low values, scrJ(2)∼13Latin small letter h with stroke2 MeV-1, approximately one-third the rigid-body value, and, contrary to expectations, the moments of inertia become nearly equal to one another and to those of rotational bands in the core nucleus Sn108.
