The 5f(3) manifold of the free-ion U3+ : Ab initio calculations
The energy levels of the 5f(3) manifold of the free-ion U3+ Up to 30 000 cm(-1) are calculated with two well stabilized ab initio methods based on the two-component Hamiltonians of Cowan-Griffin-Wood-Boring and Douglas-Kroll-Hess. Although the corresponding experimental data do not exist, estimates made out of experiments on the 50 manifold of U3+ in solids are usually referred to as the experimen
