Abstract
Superconductive Nb–Nb point contacts have been studied with 9.5‐μm radiation from CO2 lasers. Two models are considered to explain the experiments: one is Werthamer's Josephson junction model and the other is a thermally modulated Josephson junction. The evidence favors Werthamer's model but is not conclusive.Keywords
