We report detailed measurements of the fluctuation conductivity above Tc of one-dimensional aluminum microstrips. These results support a new theory by Patton which apparently resolves the recent puzzle concerning the anomalous contribution to the fluctuation conductivity reported by Maki and Thompson. Comparison of experiment with theory indicates that the samples studied are the first characterized by lifetime effects closely approaching the intrinsic limit for a BCS superconductor.
