deuteron Introduction
A deuteron is a nucleus consisting of a proton and a neutron. An isotope nucleus of hydrogen. The binding energy is 2.20 megaelectron volts. Deuterons react with other nuclides, such as tritium nuclei, to emit neutrons with low threshold energy, large cross sections, and high neutron energy. Therefore, it can be used as a neutron source material or as a fuel for nuclear fusion. The content of nature is about one-seventh of that of general hydrogen. It is produced from nuclear reactions and is mainly used in thermonuclear reactions.
