Nuclear FissionNuclear Fission

Enrico Fermi: bombarded uranium with Enrico Fermi: bombarded uranium with neutronsneutrons

Hahn and Strassman: repeated Fermi’s Hahn and Strassman: repeated Fermi’s experiment, but produced bariumexperiment, but produced barium

Lise Meitner: found reason for barium Lise Meitner: found reason for barium impurity – first to identify a nuclear fission impurity – first to identify a nuclear fission rxnrxn

Nuclear fission rxnNuclear fission rxn: a large nucleus is split : a large nucleus is split into two smaller nucleiinto two smaller nuclei
