Both atomic clusters (microclusters) and nuclei are systems of the finite number ofparticles but with different interaction forces among the component particles, and have somesimilarities in their properties, such as saturation, shell structures, magic numbers, isotopic effect,deformation and compound clusters (nuclear) process, etc.
原子团簇(或原子簇)和原子核内部粒子之间的相互作用是根本不同的,但都是含有一定数目的多粒子系统,存在着某些相似特性,如饱和性、壳结构、幻数与同位素效应、变形特性和复合团簇(核)过程等,这些相似性是核物理学家、原子物理学家以及化学家们共同关心的问题。
