Abstract
/Au point-contact junctions have been studied. For a description of junction properties we used the Blonder-Tinkham-Klapwijk theory where we included the finite lifetime of the quasiparticles. From the fitting procedures of the experimental differential characteristics, the values of the Fermi velocity ≃5× cm/s, the ratio 2Δ/ ≃8, and the coherence length ≃35 Å for were obtained.
