Abstract

The existing Nuclear Resonance Fluorescence (NRF) setup at the HI gamma S facility at the Triangle Universities Nuclear Laboratory at Duke University has been extended in order to perform gamma-gamma coincidence experiments. The new setup combines large volume LaBr3:Ce detectors and high resolution HPGe detectors in a very close geometry to offer high efficiency, high energy resolution as well as high count rate capabilities at the same time. The combination of a highly efficient gamma-ray spectroscopy setup with the mono-energetic high-intensity photon beam of HI gamma S provides a worldwide unique experimental facility to investigate the gamma-decay pattern of dipole excitations in atomic nuclei. The performance of the new setup has been assessed by studying the nucleus S-32 at 8.125 MeV beam energy. The relative gamma-decay branching ratio from the 1(+) level at 8125.4 keV to the first excited 2(+) state was determined to 15.7(3)%. (C) 2013 Elsevier B.V. All rights reserved.
