from 1961 to 1967. Walcher was a co-initiator of the Gesellschaft für Schwerionenforschung (GSI, Society for Heavy Ion Research) in Darmstadt and the Deutsches Elektronen-Synchrotron (DESY, German Electron Synchrotron) in Hamburg. In 1957, Walcher was one of the 18 signers of the Göttinger Manifest, which opposed the rearming of Germany with nuclear weapons. Honors Walcher received honors for his contributions to Germany and the German physics community: 1975 – Großes Verdienstkreuz (Great Cross of Merit) of the Verdienstorden der Bundesrepublik Deutschland (Order of Merit of the Federal Republic of Germany) 1976 – Ehrendoktorwürde der Ruhr-Universität Bochum (Honorary doctorate of the Ruhr-University Bochum) Internal Reports The following report was published in Kernphysikalische Forschungsberichte (Research Reports in Nuclear Physics), an internal publication of the German Uranverein. The reports were classified Top Secret, they had very limited distribution, and the authors were not allowed to keep copies. The reports were confiscated under the Allied Operation Alsos and sent to the United States Atomic Energy Commission for evaluation. In 1971, the reports were declassified and returned to Germany. The reports are available at the Karlsruhe Nuclear Research Center and the American Institute of Physics.
