7.Using the theoretical equations describing the I–V characteristics for superconductor‐superconductor tunneling, developed by Shapiro et al., the experimental data, obtained on the junctions, were closely simulated and showed effects due to local anisotropy. The experimental I–V curves represent an average of all energy gaps located in a cone of 2–3 deg from the primary tunneling direction as predicted by Clem for thick (50‐Å) barriers. This averaging tends to round the sharp cusp at the voltage difference in the half‐gaps and make more gradual the current rise at the voltage sum of the half‐gaps.
