- Abstract
We have calculated the strength of the excitations between the crystal-field states which are in agreement with inelastic-neutron-scattering results. This agreement confirms the existence in the heavy-fermion superconductor UPd2Al3 the crystal-field electronic structure being the finger-print of the U3+ ions with three localized f electrons forming strongly-correlated atomic-like quantum system 5f³. The ionic integrity and the low-energy crystal-field electronic structure is preserved in this metallic system in the meV scale as has been postulated in the Quantum Atomistic Solid State theory (QUASST). We provide preliminary results with the U3+ ion in UGe2 showing the ground-state eigenfunction which reproduces the ordered magnetic-moment value of 1.48 µB. This moment is composed from the dominant orbital contribution (2.6 µB) and the opposite spin moment (1.12 µB).
