A previous self-consistent calculation of energy bands in ferromagnetic nickel using the tight-binding method has been extended to include spin-orbit coupling. Exchange was incorporated using the $X\alpha$ method with $\alpha =\frac{2}{3}$. Energy levels were obtained at 1357 points in 1/16th of the Brillouin zone. The direction of spin alignment was taken to be [001]. The density of states was computed by a hybrid method. Cross sections of the Fermi surface were determined, and effective masses were obtained. The interband contribution to the conductivity tensor was calculated using matrix elements computed from wave functions including spin-orbit coupling. Results were obtained for both the diagonal and the off-diagonal elements of the conductivity tensor.
