The angular and energy structures of the nonequilibrium electron distribution function for potassium at low temperatures are investigated. It is shown that the peculiarities in the δ f k structure due to U‐processes are largely suppressed by interference between normal and U‐processes. Hence at the umklapp process freezing temperatures the value of resistivity is affected not only by U‐transitions from “hot spots” but equally by diffuse N‐transitions. The solution of Boltzmann equation by quadrature formulas is discussed.
