The single-particle matrix elements of the many-body matrix of the conduction electrons scattering by a magnetic impurities at T=0 temperature was calculated using numerical renormalization group (NMG). The total and the elastic, spin-diagonal scattering cross sections was determined by the spin-particle matrix elements. The full energy, spin and magnetic field dependence of the inelastic scattering cross section σ inel(ω) was computed. A linear frequency dependence of σinel(ω) below the Kondo temperature was found, which crosses over to ω2behavior at low energies.
