Hall coefficient in pure metals: Lowest-order calculation for Nb and Cu

Abstract
The lowest-order solution to the linearized Boltzmann equation is calculated for Nb and Cu with uniform external electric and magnetic fields. This solution corresponds to a rigid displacement of the Fermi surface, and should be accurate when the anisotropy of the electron scattering function is small. For Cu the result agrees very well with experiment. The agreement with experiment for Nb is within 14%.
