People and Things People and things Peter Koehler (seated) and Chuck Brown took over leadership of the Fermilab Research Division in October. Peter serves as Research Division Head succeeding John Peoples who has completed a five year term in the office. Peoples now joins the Accelerator Division. Chuck Brown will act as deputy head of the Division. (Photo Fermilab) Wolfgang Gentner Wolfgang Gentner died in Heidel­ berg on 4 September at the age of 74. He was an influential personality in physics for many years and played an important part in the de­ velopment of CERN and in the furtherance of physics in the Fed­ eral Republic of Germany. He was born in Frankfurt (Main) and received his physics degree there before moving to work with Marie Curie in Paris. He returned to Germany in 1935 where he be­ gan his long association with Hei­ delberg University. It was there that he made his first acquaintance with the world of accelerators, being involved in the construction of a Van de Graaff proton machine and in the design of a cyclotron. He gained cyclotron experience on the machine which Joliot had built in Paris. After the war he was nominated Director of the Institute of Physics and became its Chairman in 1968. as his work on critical phenomena, in Freiburg and it was from there He was for many years German Wilson is also widely known for his that his involvement in CERN began. delegate to the CERN Council and research in elementary particle phy­ He was party to the early discus­ from 1972-74 was President of sics.

Batavia Area Office of the U.S. Department of Energy. (Photo Fermilab) The Fermilab 400 GeV accelera­ tor, the newly commissioned PEP storage ring and the CESR facility at Cornell must be used as fully as possible to exploit for physics the large investments already made. Construction of the Energy Saver and of ISABELLE must proceed with all deliberate speed. Necessary research and development funds must be provided to ensure their success. University-based groups should receive increased support to assure vitality of their efforts on immediate experimentation and also on detector development for the future. Accelerator studies and tech­ nical research should begin imme­ diately toward the goal of starting the construction of a very large accelerator (electron energies of several hundred GeV or proton en­ ergies of WTeV or more) during the second half of this decade.

  • Der Mythos Der Deutschen Atombombe
    Langsame oder schnelle Neutronen? Der Mythos der deutschen Atombombe Prof. Dr. Manfred Popp Karlsruher Institut für Technologie Ringvorlesung zum Gedächtnis an Lise Meitner Freie Universität Berlin 29. Oktober 2018 In diesem Beitrag geht es zwar um Arbeiten zur Kernphysik in Deutschland während des 2.Weltkrieges, an denen Lise Meitner wegen ihrer Emigration 1938 nicht teilnahm. Es geht aber um das Thema Kernspaltung, zu dessen Verständnis sie wesentliches beigetragen hat, um die Arbeit vieler, gut vertrauter, ehemaliger Kollegen und letztlich um das Schicksal der deutschen Physik unter den Nationalsozialisten, die ihre geistige Heimat gewesen war. Da sie nach dem Abwurf der Bombe auf Hiroshima auch als „Mutter der Atombombe“ diffamiert wurde, ist es ihr gewiss nicht gleichgültig gewesen, wie ihr langjähriger Partner und Freund Otto Hahn und seine Kollegen während des Krieges mit dem Problem der möglichen Atombombe umgegangen sind. 1. Stand der Geschichtsschreibung Die Geschichtsschreibung über das deutsche Uranprojekt 1939-1945 ist eine Domäne amerikanischer und britischer Historiker. Für die deutschen Geschichtsforscher hatte eines der wenigen im Ergebnis harmlosen Kapitel der Geschichte des 3. Reiches keine Priorität. Unter den alliierten Historikern hat sich Mark Walker seit seiner Dissertation1 durchgesetzt. Sein Beitrag zur Geschichte der Kaiser Wilhelm-Gesellschaft im 3. Reich beginnt mit den Worten: „The Kaiser Wilhelm Institute for Physics is best known as the place where Werner Heisenberg worked on nuclear weapons for Hitler.“2 Im Jahr 2016 habe ich zum ersten Mal belegt, dass diese Schlussfolgerung auf Fehlinterpretationen der Dokumente und auf dem Ignorieren physikalischer Fakten beruht.3 Seit Walker gilt: Nicht an fehlenden Kenntnissen sei die deutsche Atombombe gescheitert, sondern nur an den ökonomischen Engpässen der deutschen Kriegswirtschaft: „An eine Bombenentwicklung wäre [...] auch bei voller Unterstützung des Regimes nicht zu denken gewesen.
