Hybridization functions of intermetallic Ce compounds with group VI elements

Among the Cerium compounds, the heavier monochalcogenides CeY (Y = S,Se,Te) of cerium provide a class of compounds which together with the heavier monopnictides CeX (X = N,P,As,Sb,Bi) exhibit extremely interesting physical properties. The hybridization of the partially delocalized f-electrons seems...
