Resonant peaks in the {ital resistance} of a mesoscopic normal-metal wire in contact with two superconductors under rf irradiation are detected. The peaks occur when a potential difference V{sub S}={h_bar}{omega}/2e is applied between the superconductors. The peaks can be interpreted as an ac phase-coherent phenomenon in the conductance of mesoscopic normal-metal{endash}superconductor structures. This effect is observed although the critical Josephson current is negligibly small and the Shapiro steps are absent. {copyright} {ital 1997} {ital The American Physical Society}
