Metal loaded liquid scintillators — •Christian Buck, F.X. Hartmann, D. Motta, S. Schönert, and U. Schwan — Max Planck Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg

The development of metal based liquid scintillator systems is important towards the next generation low energy solar neutrino, reactor anti-neutrino and double-beta decay experiments. One approach to develop stable scintillator systems containing In (solar neutrinos), Gd (reactor neutrinos) or Nd (neutrinoless double-beta decay) is the use of metal beta-diketonate complexes.

The optical properties of these metal loaded scintillators will be reported. Furthermore the energy transfer between the various components in a liquid scintillator will be discussed. The In-system was investigated in most detail. Results of a highly loaded In-scintillator used in a prototype detector at the underground laboratory in Gran Sasso, Italy will be presented.
