Proton, Captain. Fictional hero of a holodeck program created by Tom Paris. The Adventures of Captain Proton is based on old Earth film serials from the 1930s. Captain Proton is normally accompanied by his trusty sidekick, Buster.
Protons are spin â1/2 fermions and are composed of three quarks, making them baryons. The two up quarks and one down quark of the proton are held together by the strong force, mediated by gluons. Protons and neutrons are both nucleons, which may be bound by the nuclear force into atomic nuclei. The nucleus of the most common isotope of the hydrogen atom is a single proton (it contains no neutrons). The nuclei of heavy hydrogen (deuterium and tritium) contain neutrons.
