Abstract
Refinements of the curve of density of states n(E) in lead, as deduced from the de Haas-van Alphen effect, are inferred from existing superconductivity and transport data on pure lead and on Pb-Tl and Pb-Bi alloys when these data are interpreted in terms of a simple inverse transition metal model. n(E) is found to have a maximum just below the Fermi level. It is suggested that the maximum might be accounted for by supposing the multiply-connected portion of the Fermi surface to split up into separate portions as the electron concentration is reduced; however, this particular interpretation does not seem to be compatible with a model of rigid bands.
