微原子簇,即由2—10~2个原子组成的极细微粒,因其一系列特殊性质及由此带来的潜在应用前景,80年代以来已成为物理、化学和材料科学三者交叉的一个活跃研究领域。库仑爆炸(Coulombic explosion)是微原子簇特有的奇异性质之一。实验发现,某些荷正电的原子簇(簇正离子)M_n~m(m≥2),当簇尺寸小于某一临界值n_c时将裂解成若干带单电荷和电中性的碎片。近年报道的簇离子n_c值测定数据常因实验方法和条件的不同而有较大的差异。主要原
Micro-atom clusters, that is, fine particles of 2-10 or 2 atoms, have become the cross between physics, chemistry and materials science since the 1980s due to a series of special properties and the potential application prospects An active research area. Coulombic explosion is one of the unique singular properties of micro-atomic clusters. Experiments show that some positively charged clusters (cluster positive ions) M_n ~ m (m ≥ 2), when the cluster size is smaller than a certain critical value n_c will be cracked into several with single charge and neutral charge. In recent years reported clustered ion n_c value of the data often due to experimental methods and conditions are quite different. The main original
