The first scientist to split the atom was the New Zealander Ernest Rutherford<\/a> in 1917. On January 31 of that same year, the Germans Otto Hahn and Lise Meitner discovered protactinium<\/a>, a radioactive element produced in uranium's disintegration.<\/p>\n\n\n\n

In 1938, the team of the two researchers and Fritz Strassmann<\/a> discovered nuclear fission by realizing that if they bombarded uranium with neutrons, they obtained barium. Hahn would win the Nobel Prize in Chemistry for this discovery a year later.<\/p>\n\n\n\n

The discovery crossed the Atlantic and reached Columbia University, where in January 1939 they carried out the first nuclear fission experiment in the United States.<\/p>\n","protected":false},"excerpt":{"rendered":"
