An analysis of neutron scattering spectroscopy in UO2

A calculation has been performed to analyse neutron scattering spectrum of an ion with f2 configuration in a cubic crystal field. The present analysis, using a six-interaction Hamiltonian, gives an energy-level fit which has a rms σ=15.1 relative to the experimentally observed crystal field excitations. The wave functions thus obtained were used to calculate the effective magnetic moment of UO2. The final values of the interaction parameters are given. (orig.)
