dc.descriptionWe present the results of inelastic neutron scattering measurements, performed near the antiferromagnetic quantum critical point in Ce(Ru_{0.24} Fe_{0.76})_2 Ge_2. Both local and long range fluctuations of the local moments are observed, but due to the Kondo effect only the latter are critical. We propose a phenomenological expression which fits the energy $E$, temperature T and wave vector q dependences of the generalized susceptibility chi(q,E,T), describing the non-Fermi liquid E/T scaling found at every wave vector.
