Abstract

The paper compares the K-dependence of the superconducting gap in different doping ranges. The fine behavior of the leading edge gap indicates that the pairing susceptibility is peaked at special regions on the Fermi surface. These hot regions are found to be centered away from nominal "hot spots". This behavior is attributed to a feedback effect on the pairing boson. Identification is made through comparison with neutron diffraction results.
