The word "deuteron" refers to a type of particle found in the nucleus of an atom, specifically the nucleus of a hydrogen atom. It consists of one proton and one neutron. Full definition
Using the same principle, researchers today replace protons with deuterons in organic compounds, to pin down the way molecules are arranged in, for example, thin films. (newscientist.com)
We accelerated deuterons in one direction, gold nuclei in the other direction, and then recorded the collision products when they smashed together. (aaas.org)
H - bombs fuse together tiny hydrogen nuclei known as deuterons and tritons to create helium nuclei, along with the most powerful explosions in the human arsenal. (scientificamerican.com)
