Two methods of parameter determination for a complicated dispersion relation of electrons in bismuth are applied. The dispersion relation employed is obtained by Abrikosov and Falkovskii on the basis of a deformation theory. Discrepancies remaining with respect to energy dispersion in the direction of elongation of the electron part of Fermi surface are analysed and compared with k · p ‐model considerations. An extended form of the Abrikosov‐Falkovskii model is presented, which should provide a more precise description of the topology of the electron Fermi surface.
