It is not uncommon for a cosmic ray to collide with an atom in the atmosphere, creating a secondary cosmic ray in the form of an energetic neutron, and for these energetic neutrons to collide with nitrogen atoms. Co­smic rays enter the earth's atmosphere in large numbers every day. In 14 C decay, a neutron transforms into a proton and an electron.
