B 43, 3137 (1991)] Eriksson et al. conclude that the alpha-phase is best described as a delocalized 4f-electron system. We show that the limited experimental evidences provided in support of this statement are not conclusive and do not allow one to discard the single-impurity model, which is consistent with all spectroscopic data.TransitionCeriumtext::journal::journal article::research article
