Abstract

The Brovman-Kagan-Kholas pseudopotential is used to calculate the electron-phonon interaction functions G(ω)=α^2(ω)F(ω) in the alkali metals Na and K. The functions obtained are in satisfactory agreement with the point-contact spectra (i.e., the d2V/ dI2-versus-V curves) of these metals. The anisotropy of the G-function is determined. This is, however, found to have a relatively small magnitude.
