摘要: The discovery by Rutherford in 1919 that \(\alpha \)-particles could induce nuclear reactions and transform isotopes elements opened up the possibility to produce new laboratory. However, only after of neutron Chadwick 1932 was nucleus understood terms consisting neutrons protons. chapter describes radioactive 1930s produced with \) sources as well first accelerators. complicated history fission is also included.
