Double-Gamma Nuclear Decay Experiments using Active Compton Supression — •Martin Baumann1, Thomas Aumann1,2, Michael Beckstein1, Patrick Van Beek1, Daniel Körper2, Bastian Löher2, Heiko Scheit1, and Dmytro Symochko1 — 1Institut für Kernphysik, TU Darmstadt, Germany — 2GSI Helmholtzzentrum, Darmstadt, Germany
The 4π Nai detector array Heidelberg-Darmstadt Crystal Ball has been upgraded with 16 LaBr3 detectors and a specially developed compton suppression system called BACCHUS. This made possible double gamma decay measurements with significantly reduced measuring time in comparison to previous experiments. Also the angular distribution between the two emitted photons can now be probed for a larger set of angles. The 11/2− → 3/2+ transiton of 137-Ba is used as a benchmark to characterise the setup and evaluate future possible uses.
