Renormalized Atoms and the Band Structure of Transition Metals

A microscopic interpretation of εd, the mean d-band energy in the Heine-Hubbard interpolation description of the transition metals, and of ε(Γ₁), the bottom of the conduction bands, is given in terms of a "renormalized atom" concept. The implication for the cohesive energy of the transition metals is considered within the same framework and contrasted to the alkali metals.
