Abstract : Examination of available tunneling data from junctions oriented on single crystal niobium, shows that the observed superconducting energy gap values are grouped non-randomly in K-space. These groupings suggest a relationship between delta (K) and Fermi surface topology, and may suggest a significant role for phonon anisotropy. (Author)
