摘要：

Detailed calculations are presented for the superconducting gap and critical temperature of a van Hove superconductor. The calculations are modified to account for a number of complicating factors, including interlayer coupling, strong coupling, and depairing effects due to real phonon scattering and spin scattering. The calculations are compared to experimental data on the isotope effect, spin-lattice relaxation time T1, and magnetic penetration depth, and satisfactory agreement is found. Power law corrections, particularly in T1, are suggestive of a gap zero.
