1939 1 28, the University of Rome, Enrico - Fermi theoretical physicists meeting in Washington at the atomic explosion can release 200 million volts of energy. The Fermi say this huge energy emanating German scientist Otto - Hahn in an experiment using neutron bombardment called artificial synthesis of elements of prospective uranium.
