确定了过渡金属团簇的局域轨道矩和平均轨道矩，填补了原子Hund规则和固态猝灭之间的差距。一个显着的增强显示与最近的测量结果一致。在小的Ni（N）（N或=150）显示几乎块状淬火在内部，但保留了相当大的表面增强。不同的TM的趋势进行了讨论。
The local and average orbital moments of transition-metal (TM) clusters are determined bridging the gap between atomic Hund's rules and solid-state quenching. A remarkable enhancement of is revealed in agreement with recent measurements. In small Ni(N) (N or =150) show nearly bulklike quenching at the interior but retain a considerable surface enhancement. Trends for different TM's are discussed.
