spin
noun (Concise Encyclopedia)Amount of angular momentum associated with a subatomic particle or nucleus. It is measured in multiples of {Planck constant} (h-bar), equal to Planck's constant divided by 2. Electrons, neutrons, and protons have a spin of , for example, while pions and helium nuclei have zero spin.
