Abstract. Hall-effect and magnetoresistivity of electrons in multi-valley bands of Si and Ge is considered with due regard for direct intervalley drag. Search of contribution of this drag shows that this interactioin sufficiently changes both effects. Calculated here values substantially differ from consequent those obtained on the base of popular - approximation.

Keywords: quantum kinetic equation, Hall-effect, mobility, intervalley drag.
