讨论了f轨道与相邻位置上的非f配体之间的杂化是决定某些Ce和U化合物，包括重费米子金属的带宽和性质的主要机制。用这一杂化机制解释了重费密子及其相关行为在元素周期表中的出现和系统变化，并对U${X}_{3}$化合物的实验数据进行了具体讨论。建议进行几个实验来澄清和扩展这些想法。
Hybridization between f orbitals and non-f ligands on neighboring sites is discussed as the primary mechanism determining the bandwidth and properties of certain Ce and U compounds, including the heavy-fermion metals. The occurrence and systematic variation of heavy-fermion and related behavior in the Periodic Table is interpreted in terms of this hybridization mechanism, with a specific discussion of experimental data for the U${X}_{3}$ compounds. Several experiments are suggested to clarify and extend these ideas.
