Meitner–Frisch interpretation of fission

E159822

The Meitner–Frisch interpretation of fission is the 1939 theoretical explanation by Lise Meitner and Otto Frisch that identified nuclear fission as the splitting of heavy atomic nuclei with a corresponding release of enormous energy, laying the groundwork for nuclear physics and atomic energy.
