WebDiscovery of nuclear fission in Berlin 1938 D HILSCHER Hahn-Meitner-Institut Berlin, D-1000 Berlin 39, FRG Abstract. The story of the discovery of nuclear fission, one of the most exciting stories of how a scientific puzzle was finally solved and how the scientists involved were blind to many obvious indications, is described. ... WebEn 1938, Otto Hahn et Fritz Strassmann ont découvert la fission nucléaire, qui a conduit au développement de la bombe atomique pendant la Seconde Guerre mondiale. En 1952, les physiciens ont réussi à produire la première réaction de fusion nucléaire contrôlée, qui a ouvert la voie à la production d'énergie nucléaire.
