Abstract
Electronic energy spectra in deformed crystals are studied by a perturbation method according to the scheme of Pikus and Bir. Terms of order k2eij are included in addition. An analytical expression is obtained for the deformation dependence of a carrier effective mass in a case of no degeneracy.
