Abstract
We examine the periodic disappearance of superconductivity in a mesoscopic superconducting ring whose radius is close to the zero-temperature coherenc e length. We have used energy gap measurement by small tunnel junctions. We find that the amplitude of the Little-Parks oscillation is smaller than th at predicted from the Ginzburg-Landau theory.
