摘要：

Copious vortex line creation in a fast (approximately 3 ms) adiabatic expansion of a volume of liquid He-4 through the lambda transition has been observed. The maximum line density, inferred from measurements of second sound attenuation, is found to be much larger than that in a comparable expansion from just below the lambda line. The phenomenon was predicted by Zurek who proposed it as a model of cosmic string creation in the false vacuum/true vacuum phase transition of the early universe.
