Hahn and Strassmann at the Kaiser Wilhelm Institute for Chemistry in Berlin bombardeduranium with slow neutrons and discovered that barium had been produced. Hahn suggested a bursting of the nucleus, but he was unsure of what the physical basis for the results were.
Otto Hahn, Lise Meitner, and Fritz Strassmann
In 1938 Hahn, Meitner, and Strassmann became the first to recognize that the uranium atom, when bombarded by neutrons, actually split. Hahn received the Nobel Prize in Chemistry in 1944.
Manhattan Project: The Discovery of Fission, 1938-1939 - OSTI.GOV
It was December 1938 when the radiochemists Otto Hahn (above, with Lise Meitner) and Fritz Strassmann, while bombarding elements with neutrons in their Berlin laboratory, made their unexpected discovery.
Discovery of Nuclear Fission - American Physical Society
In December 1938, Hahn and Strassmann, continuing their experiments bombarding uranium with neutrons, found what appeared to be isotopes of barium among the decay products. They couldn’t explain it, since it was thought that a tiny neutron couldn't possibly cause the nucleus to crack in two to produce much lighter elements.
The Discovery of Fission - Atomic Archive
The radiochemists Otto Hahn and Fritz Strassmann were bombarding elements with neutrons in their Berlin laboratory when they made an unexpected discovery. They found that while the nuclei of most elements changed somewhat during neutron bombardment, uranium nuclei changed greatly and broke into two roughly equal pieces.
Pioneering Nuclear Science: The Discovery of Nuclear Fission
75 years ago three scientists Dr. Otto Hahn, Dr. Lise Meitner and Dr. Fritz Strassman working at the Kaiser Wilhelm Institute for Chemistry in Berlin developed an experiment grounded on the then-evolving concept that splitting an atom of an element would produce two atoms of smaller different elements.
4: The Discovery of Fission (1938) - Chemistry LibreTexts
Early in December 1938, Hahn and Strassmann thought that they had established the nuclear reactions that yielded the products observed by the Joliot-Curies. Presumably, isotopes of radium produced by the initial neutron bombardment of uranium decayed to thorium and actinium.
Hahn, Meitner and the discovery of nuclear fission
The combination of Hahn’s expertise in chemistry with Meitner’s in physics opened the door to artificially induced nuclear fission. And when Meitner fled from Nazi persecution in 1938, Hahn ...
The Discovery of Nuclear Fission - MPIC
While bombarding uranium with neutrons, Otto Hahn and his colleague Fritz Straßmann discovered that fission products such as barium were also created in the process. In January 1939, Lise Meitner and her nephew Otto Frisch provided the explanation.
Fritz Strassmann - Wikipedia
Friedrich Wilhelm Strassmann (German: [fʁɪt͡s ˈʃtʁasˌman] ⓘ; 22 February 1902 – 22 April 1980) was a German chemist who, with Otto Hahn in December 1938, identified the element barium as a product of the bombardment of uranium with neutrons.
