New polarized beam measurements have been carried out in the paramagnetic phase of 60Ni in order to enlarge the (q,ω) range previously studied by Steinsvoll et al. Magnetic scattering has been detected up to halfway to the zone boundary. The results can be successfully interpreted in terms of a diffusive-type scattering function over an unexpected wide (q,ω) range q<0.5 Å-1 and ω<80 meV. The neutron data are also compared with the predictions of the very recent band model by Callaway. Finally, we point out important similarities and differences in the paramagnetic scattering from localized systems, such as EuO, and itinerant systems and discuss the universality of the paramagnetic scattering function.
