As shown by the LDA+U+Hubbard I calculations, its intensity scales with the admixture of the 5f6 manifold in the 5f5 ground state, which can lead to an average occupancy substantially exceeding 5.0. This admixture also leads to the suppression of magnetic order and occurrence of heavy fermion behaviour.
