Abstract

The large multidetector gamma-ray arrays (such as GAMMASPHERE, EUROBALL, and GASP) have played a central role in nuclear-structure studies during the past decade. In this paper I will discuss recent results from experiments on nuclei with very large deformations, including: the measurement of the spins, parities, and excitation energies of superdeformed bands in ¹⁵² Dy; the observation of extreme deformations in ¹⁰⁸ Cd and the evidence for hyper-intruder states; the study of superdeformed nuclei around , which provide an opportunity to test our microscopic understanding of collective excitations; and lifetimes of strongly deformed triaxial bands in ¹⁶³ Lu. I will conclude with a brief discussion on the next generation gamma-ray detector array, GRETA.
