摘要: Directional electron-phonon effective distribution functions ..cap alpha../sup 2//sub k/(..omega..) F/sub have been calculated at many points on the Pb Fermi surface. From these distributions zero-temperature energy gaps in superconducting single crystals follow from one iteration of directional Eliashberg equations. Anisotropic mass renormalization parameters are also determined. In calculated, surface is obtained a four-plane-wave model pseudopotential chose to fit de Haas-van Alphen data. The electron states used evaluating interaction which addition depends lattice dynamics. This taken experiments dispersion curves for phonons. (AIP)
