We report resistance oscillations as a function of magnetic field for individual aluminum and silver thin-film rings, 1-2 m in diameter, between 1.2 and 10 K. This is the first observation in single rings of oscillations with a flux period of h2e predicted by Al'tshuler et al. Oscillations periodic in he are also seen in the 1-m Ag rings at higher fields. These electron interference effects in metal rings are the solid-state analog of the Aharonov-Bohm effect for electrons in vacuum.
