ABSTRACT —A review is made of some of the frontiers in nuclear research with heavy ions. Recent results from studies of nuclei far from stability, very high spin states and nuclear molecules with Z= 184 are given. New applications of nuclear techniques in medicine, positron emission tomography and nuclear magnetic resonance, also are presented.
