在一个孤立的原子中，外部价壳层之上的内部价电子的激发导致了自电离状态的产生。最近，实验证明，在团簇中，内价激发态也可以通过一种被称为共振原子间库仑衰变（RICD）的原子间机制衰变。我们证明RICD确实是团簇内价激发的主要而不是唯一可能的原子间衰变模式。以Ne （2s—>3p）在MgNe团簇中的激发为例，探讨了可能的衰变机制，并得出了它们的相对重要性和相应衰变产物的性质。
In an isolated atom, excitation of an inner valence electron above the outer valence subshell leads to creation of an autoionizing state. Recently, it has been demonstrated experimentally that in a cluster, the inner-valence-excited states can decay also by an interatomic mechanism which has been called resonant interatomic Coulombic decay (RICD). Here we show that RICD is indeed the leading but not the only possible interatomic decay mode of the inner-valence excitations in clusters. Using Ne (2s-->3p) excitation in MgNe cluster as an example, we explore the possible decay mechanisms and draw conclusions on their relative importance and on the nature of the corresponding decay products.
