Abstract
Phase transitions create a domain structure with defects, which has been argued by Zurek and Kibble (ZK) to depend in a characteristic way on the quench rate. We present an experiment to measure the ZK scaling exponent . Using long symmetric Josephson tunnel junctions, for which the predicted index is , we find . Further, we agree with the ZK prediction for the overall normalization.
