Abstract
Nuclear physics is advancing rapidly at the precision frontier, where measurements of nuclear observables are challenging state-of-the-art nuclear models. A major contribution is associated with the increasing availability of accelerated beams of radioactive ions produced using the isotope separation on-line technique. These advances have come hand in hand with significant progress in the development of high-efficiency detector systems and improved target technologies which are invaluable in exploiting these beams to their full advantage. This article reviews some of the recent highlights in the field of nuclear structure profiting from these technological advances.
