There is an error in the illustration. Two deuterium nuclei are shown reacting and yielding a helium-3 nucleus and energy. There are four nucleons in two deuterium nuclei, three in a helium-3 nucleus. The number of nucleons should be the same before and after the reaction. In this reaction a neutron should be shown among the products; i.e., two deuterieum nuclei can react to yield a helium-3 nucleus, a neutron, and energy.
