摘要：
Experimental data concerning the supercurrent decay of underdamped Josephson junctions are compared with the Kramers theory on the decay of a metastable state, and some of its recent improvements. The comparison between data and theory is performed with no free fitting parameters, and significative aspects of the cross-over region between the extremely underdamped regime and the moderate underdamped one are investigated.
