Influence of Electron Interactions on Metallic Properties

The influence of electron interactions on the one-electron energy in metals is calculated. The calculation is based on the Bohm-Pines collective description of electron interactions and has for its principal approximation the treatment of the screened interaction Hₒₑ by perturbation theory. Results are given for the band width, specific heat, relaxation time, conductivity, thermoelectric power, and diamagnetic susceptibility. Comparison with experimental values of band width and specific heat for the alkali metals shows satisfactory agreement. Density-of-states plots for the alkalis are given.
