  The well known quadratic low-temperature dependence of resistance in ordinary
metals habitually serves as the criterium of applicability of the Landau Fermi
liquid theory to the description of electron liquid in concrete material. Such
a type of behavior is determined by momentum relaxation due to the
electron-electron scattering.Here I consider this problem in the metals without
inversion center. It is shown that the corresponding scattering time at
temperatures much smaller than the spin-orbit coupling is practically
temperature independent.
