摘要：

This Letter examines new types of localization sites for an excess electron in finite alkali-halide clusters resulting from defects on cuboidal structures, namely ''edge states,'' R center, and other surface defects. We present theoretical calculations on NanFn-1 clusters with one excess electron. Comparisons with experimental results are presented for different cluster sizes (n = 17, 23, 28, and 29). Structures with edge or surface defects are relevant for n = 23, 28, and 29.
