<Otto Robert Frisch> and <Lise Meitner> interpreted the <barium> found after <uranium> bombardment as evidence that a heavy <atomic nucleus> could divide into two large fragments. Their 1939 paper related the available <energy> to nuclear mass differences and the electrical repulsion of the fragments. This supplied a physical account of <nuclear fission>, connecting a chemical identification of the products with a new type of nuclear transformation and its large energy release.<Disintegration of Uranium by Neutrons: a New Type of Nuclear Reaction by Lise Meitner and Otto Robert Frisch>[1939 Nature paper, interpretation of barium and energy estimate]{ref}
