    Diagram of the D-T reaction. The easiest nuclear reaction, at the lowest energy, is D+T: 2 1 D + 3 1 T → 4 2 He (3.5 MeV) + 1 0 n (14.1 MeV) This reaction is common in research, industrial and military applications, usually as a neutron source. Deuterium is a naturally occurring isotope of hydrogen and is commonly available.
