Abstract:	Inelastic neutron scattering studies were performed in the paramagnetic phases of several rare earth compounds that crystallize in the cubic Cu₃Au structure: ErPb₃, ErTl₃, ErIn₃, HoPb₃, HoTl₃, HoIn₃, PrSn₃, PrPb₃, PrTl₃, PrIn₃, CeIn₃, La_1–cPr_cTl₃, and Pr(In_0.5Tl_0.5)₃. The energies, widths and intensities of the crystal field excitations are determined and discussed in terms of interactions between the rare earth ions. Variations of the crystal field parameters are observed across the series.Work partially supported by the BMFT
