Description
During 2012/2013 the GRETINA gamma-ray spectrometer has been installed at the S800 spectrograph at the National Superconducting Cyclotron Laboratory (NSCL). The GRETINA array is the first critical step towards a full 4pi GRETA device. Its high angular and energy resolution provide the necessary position resolution for Doppler correction at intermediate beam energies and allow for the rejection of Compton scattering events to reduce the background. The physics program at the NSCL includes a wide range of topics in nuclear structure and nuclear astrophysics. The combination of intense rare isotope beams and state-of-the-art detection devices allows for spectroscopic studies of exotic nuclei far from stability. Over the period of one year 23 experiments have been performed investigating single-particle and collective properties of rare isotopes. In this talk I will present an overview of the GRETINA physics program at NSCL and report on first results from experiments studying nuclei across the nuclear chart.
