Determination of metallic sodium Hall coefficient from ''primary principles''

The Hall coefficient R(T) has been determined for sodium with the spherical Fermi surface under the conditions of a weak magnetic field and from ''primary principles'' using the quasi-classical kinetic equation in the temperature range of 3 <= T <= 100 K. Theoretical and experimental values of R(T) are shown to coincide with a reasonable accuracy. The R(T) curve asymmetry, relative scale of R changing in the investigated temperature integral and also the R maximum location on a temperature scale have been described in a proper way. Theoretical description of experimental data turned out to be possible only because of simultaneous consideration of thin angular and energetic structures of non-equilibrium part of the elecronic distribution function
