Beschreibungen/Notizen

• A high-granularity mixed spectrometer consisting of high-resolution Ge and very fast LaBr3(Ce)-scintillator detectors has been installed around a fission target at the cold-neutron guide PF1B of the high-flux reactor of the Institut Laue–Langevin. Lifetimes of excited states in the range of 10ps to 10ns can be measured in around 100 exotic neutron-rich fission fragments using Ge-gated LaBr3(Ce)–LaBr3(Ce) or Ge–Ge–LaBr3(Ce)–LaBr3(Ce) coincidences. We report on various characteristics of the EXILL&FATIMA spectrometer for the energy range of 40keV up to 6.8MeV and present results of ps-lifetime test measurements in a fission fragment. The results are discussed with respect to possible systematic errors induced by background contributions.
