  Taking into account the long-ranged spin interactions due to weak
localization effects in disordered itinerant ferromagnets the scattering of
both electrons and neutrons on critical spin fluctuations near quantum phase
transition is considered. It is shown that for the case of low electron
density, when k_F \xi \ll 1, where k_F is the Fermi momentum and \xi is the
magnetic correlation length, the transport cross section of electrons is
proportional to conventional critical fluctuations in absence of weak
localization effects. However, the intensity of the multiple small-angle
neutron scattering becomes exponentially small as compared with the intensity
of the multiple scattering by conventional critical fluctuations.
