In 1934 Frederic and Irene Joliot-Curie were the first to produce artificial radioactivity by bombarding stable isotopes (boron and aluminum) with alpha particles (emitted as positively charged helium nuclei from polonium), which converted the original isotopes into unstable, radioactive forms. ^en

Enrico Fermi

Previous Sentence /base/kwebbase/kwsentence/previous_sentence

His theory was published in 1933-34 and had far-reaching consequences for the future development of nuclear and particle physics.

Next Sentence /base/kwebbase/kwsentence/next_sentence

Impressed, Fermi reasoned that this type of experiment might be even more effective if neutrons, rather than alpha particles, were used as the "bullets" because neutrons have no electrical charge and so are not repelled by either the negatively charged electrons or the positively charged nuclei in an atom.
