The discovery of the psi-meson was the first evidence of a nonrelativistic quark system, and is modeled as a bound system of charmed quark and charmed antiquark, called charmonium. Still heavier quarks systems have been discovered in bottomonium, with evidence of the states naked charm and naked bottom. Net spin and total angular momentum in quarkonium and singlet and doublet state configurations are reviewed, and the annihilation of the reversed-charged pairs are noted to be described by wave functions which yield the probability that the two opposite charge particles in a system will coincide in one place. Quantum chromodynamic descriptions are provided for the interactions occurring between approaching quarks and their gluon-borne color forces, and the detection of quarks in annihilation reactions, when virtual particles are created in accordance with predictions, is outlined.
