The most abundant geometries and relative stabilities of alkali halide clusters with a (XY)(n) (o) configuration (e.g., LiF, NaCl, KBr) are described. Five main series were obtained: linear, cyclic, cubic, arc strips and nanotubes. The stability analysis shows that higher members are likely to be formed from the lower member of the same series and/or from two building blocks (n = 1, 2). The energy analysis (D-plot) indicates that the most compact ones (e.g., cubic and nanotubes) present higher stability when compared to the linear, cyclic and arc strip structures; moreover, relative stability between the cubic and nanotube series varies with the cluster size.

快速离子撞击产生的碱卤化物簇。

描述了具有 (XY)(n) (o) 构型（例如 LiF、NaCl、KBr）的碱金属卤化物簇的最丰富的几何形状和相对稳定性。获得了五个主要系列：线性、环状、立方、弧带和纳米管。稳定性分析表明，较高的成员可能由同一系列的较低成员和/或由两个构建块 (n = 1, 2) 形成。能量分析（D-plot）表明，与线性、环状和弧形条带结构相比，最紧凑的结构（例如立方体和纳米管）表现出更高的稳定性；此外，立方体和纳米管系列之间的相对稳定性随簇大小而变化。
