Nuclear Fission and its Implications
When the neutron and its properties were discovered in 1932, the possibility of new types of nuclear reactions became apparent. The fact that neutrons are extremely small and have no charge makes them ideal nuclear missiles over a large range of energies. We have seen how this led to the production of radioisotopes among light elements and when Fermi in 1934 irradiated the heavier elements, notably uranium, with slow neutrons, many of the products were β−-active, as had been experienced earlier with lighter elements.
