Structure-Induced Minimum in the Average Spectrum of a Liquid or Amorphous Metal

Nonperturbative multiple-scattering theory is used to study the influence of the first peak in the density correlation function, s (k), on the electronic properties of a structurally disordered metal. The present calculations yield a well-defined minimum in the average density of states and a corresponding peak in the electrical resistivity. The position of these structures is directly related to that of the principal peak in s (k).
