Neutron intermultiplet spectroscopy has been used to re-examine UPd3 and UPt3 at 17 K. In UPd3, the H-3(4) --> F-3(2) transition is observed at 395 meV, confirming a localised 5f(2) state for the uranium ions. In the heavy fermion compound UPt3, only a small trace of this transition remains, indicating that the 5f electrons in this material are of a predominantly itinerant nature. The Q dependence of the transition in UPd3 has also been determined. The transition intensities are found to differ by a factor of similar to 2 from that predicted by calculations.
