应用于金属团簇的统计测量：幻数的证据
Statistical measures applied to metal clusters: evidence of magic numbers
摘要：
在这项工作中，一个壳层模型的金属团簇高达220个价电子被用来获得电子轨道的分数占领概率。然后，进行复杂性的统计度量和Fisher-Shannon信息的计算。这两个幅度的增加与价电子的数量进行观察。壳结构反映了统计复杂性的行为。幻数由Fisher-Shannon信息表示。因此，与原子核的情况一样，统计指标的研究也揭示了金属团簇中幻数的存在。
英文摘要：
In this work, a shell model for metal clusters up to 220 valence electrons is used to obtain the fractional occupation probabilities of the electronic orbitals. Then, the calculation of a statistical measure of complexity and the Fisher-Shannon information is carried out. An increase of both magnitudes with the number of valence electrons is observed. The shell structure is reflected by the behavior of the statistical complexity. The magic numbers are indicated by the Fisher-Shannon information. So, as in the case of atomic nuclei, the study of statistical indicators also unveil the existence of magic numbers in metal clusters.
