  • The team began investigating neutron-induced uranium decay

  • In 1934, uranium, with an atomic number of 92, had the most protons of any known element. But that year, Italian physicist Enrico Fermi believed he had synthesized elements with atomic numbers beyond the limit recognized on the periodic table.

  • Hahn was sure of the chemical evidence of transuranes

  • The political situation in Germany became dangerous for meitner, because she was of Jewish descent.

  • Nuclear investigators collaborated to provide an explanation for the results of uranium's forced transformation

  • On January 3, 1939, she wrote to Hahn
