Abstract

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 s = 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 interaction parameters (in cm^-1) are F₂ = 230.84, F₄ = 39.22, F₆ = 3.77, ?_5f = 1968, a = 34.87, ß = - 565.68, ? = 799.07, M⁰ = 0.570, M² = 0.318, M⁴ = 0.222, A₄4> = - 900.6, A₆6> = 195.4. © 1998 Elsevier Science B.V.
