Resumen:
In this paper the authors report an experimental observation of energy gap enhancement in tin. Because the energy gap does not appear directly in the I-V characteristic of a microbridge, they have measured the subharmonic gap structure, which is readily observed in the I-V characteristic and from this data they have estimated the energy gap. The microbridges were prepared by a new technique. The data is compared to the predictions of the Eliashberg theory.
