We discuss Scanning Tunneling Microscopy and Spectroscopy (STM/S) measurements at very low temperatures in single crystals of the non magnetic borocarbide superconductors RNi 2 B 2 C ( R = Y , Lu , T c=15.5 and 16.5 K) and in MgB 2. The tunneling spectra in some regions of the surface show a clear reduction of the anisotropy of the superconducting gap.
