Using e+e- annihilation data taken with the CLEO-c detector, measurements of two major Ω- branching fractions have been made using the reaction ψ(2S)→Ω-Ω.+. The Ω- decay channels are identified through momentum distributions of charged particles, and systematics of the Ω- branching fractions have been studied. The results are B(Ω-→Λ0K-)=(68.9±9.5±4.3)% and B(Ω-→Ξ0π-)=(19.0±4.0±1.2)%.
