Neutrons have no electrical charge, however, so they are not repelled by the nucleus. Hence bombardment with neutrons is a much easier way to prepare new isotopes of the lighter elements. In fact, carbon-14 is formed naturally in the atmosphere by bombarding nitrogen-14 with neutrons generated by cosmic rays:

1.Discovery of the neutron

wood were slowing the neutrons and so increasing the chance for the neutron to interact with nuclei. Fermi therefore passed neutrons through paraffin wax of the neutron


The number of neutrons defines the isotope of the element. For example, a copper atom with 34 neutrons is copper-63 (29+34), and with 36 neutrons is
