Abstract

Following the observation that the specific heat of Ce_0.7Th_0.3RhSb shows non-Fermi liquid behavior, we have investigated the inelastic neutron scattering from this compound over the temperature range 10-100 K, using the HET spectrometer at ISIS. We have found that the spectral function of Ce_0.7Th_0.3RhSb displays a power law dependence of energy, i.e. S(ω) ∼ ω^-α, with α = 0.33. The dynamical susceptibility obtained from the inelastic scattering spectra displays E/T scaling behavior as in other compounds showing non-Fermi liquid behavior. With increasing energy transfer above 10 meV, Ce_0.7Th_0.3RhSb shows a more localized behavior with two broad crystalline electric field transitions around 20 and 30 meV.
