 But it was Bohr who electrified the audience with his news from Europe of the discovery by Lise Meitner and Otto Frisch of nuclear fission . Physicists rushed to confirm the results . Creutz built an ionization chamber and a linear amplifier out of radio vacuum tubes , coffee cans and motorcycle batteries , and with this apparatus the physicists at Princeton were able to confirm the results .
