Web4: The Discovery of Fission (1938) From 1935-1938, Hahn, Strassmann, and Meitner in Germany identified at least 10 radioactive products resulting from the neutron bombardment of uranium, many more than Fermi’s group in Italy had observed initially. They assumed that these substances were new transuranic elements or isotopes of uranium. 5. Nuclear fission was discovered in December 1938 by chemists Otto Hahn and Fritz Strassmann and physicists Lise Meitner and Otto Robert Frisch. Fission is a nuclear reaction or radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei and often other particles.
