Physical Detection of Nuclear Fission Fragments
1939Frisch, "Physical Evidence for the Division of Heavy Nuclei under Neutron Bombardment" (Nature 143, 276, 18 February 1939; DOI 10.1038/143276a0). A one-page physical (non-chemical) experimental confirmation that neutron-bombarded uranium nuclei divide into energetic fragments, independent of Hahn and Strassmann's chemical route. Kept as its own node rather than folded into the Meitner-Frisch interpretation because it is a separate citable empirical result with a different method and a single author (Tier 1 SS4).
