✦ Synopsis

The point-contact of tunnel type transition has been realized on fresh cleavages of the Bi2Sr2CaCu208 single crystal. The deviation from the BCS dependence of tunneling characteristics may rather be due to nonideal barrier properties than to the nature of HTSC. Also, we have obtained the maximum ratio 23/kTc = 5.6-T-0.5 for Bi2Sr2CaCu2Os.
