Gamma spectroscopy with AGATA: New insights in nuclear excitations along the nuclear chart — •Peter Reiter — University of Cologne, Institute of Nuclear Physics

The Advanced GAmma Tracking Array AGATA is a next generation high-resolution gamma-ray spectrometer for nuclear structure studies based on the novel principle of gamma-ray tracking. It is built from high-fold segmented germanium detectors that will operate in position-sensitive mode by employing digital electronics and pulse-shape decomposition algorithms. The unique combination of highest detection efficiency and position sensitivity allows studies with radioactive ion beams of lowest intensity. A growing number of AGATA modules was exploited in the leading infrastructures GANIL, GSI and LNL for nuclear structure studies in Europe. The performed experiments give insights into nuclear structure issues which are connected to single particles, collective degrees of freedom, nucleon interactions and symmetries. Most of the investigated nuclei are located outside the stability line and for stable nuclei the investigations concern unexplored configurations. Altogether the obtained results represent advances which could test theory in exclusive way and motivate new theoretical developments. Opportunities for future investigations with the foreseen more advanced phase of AGATA will be presented.
