The decay rates of {ital c{bar c}} and {ital b{bar b}} through two-photon or two-gluon annihilations are obtained by using totally relativistic decay amplitudes and a sophisticated quantum-chromodynamic potential model for heavy quarkonia. Our results for the photonic and gluonic widths of the {sup 1}{ital S}{sub 0}, {sup 3}{ital P}{sub 0}, and the {sup 3}{ital P}{sub 2} states are in excellent agreement with the available experimental data. The procedures and mathematical techniques used by us for the treatment of the fermion-antifermion bound states are also applicable to other decay processes. {copyright} {ital 1996 The American Physical Society.}
