"The research team employed instruments of the Institut Laue-Langevin in France, the spallation source SINQ at the Swiss Paul Scherrer Institute, the UK's ISIS neutron and muon source, and the Research Neutron Source Heim Maier-Leibnitz (FRM II) at the Technical University of Munich. Further work on theory and data analysis was carried out at the U.S. Los Alamos National Laboratory and the Karlsruhe Institute of Technology"
