金属纳米团簇的能壳结构与几何结构的关联:准共振态,同位素效应

Correlation between the energy shell structure and geometry in metallic nanoclusters: quasi-resonance states, isotope effect

Vladimir Kresin

摘要:

具有电子壳层结构的金属纳米团簇表现出其几何形状与离域电子数相关的特殊性质。它们的形状演化可以被描述为准共振态(扁长和扁圆配置)之间的量子振荡,其振幅取决于壳层填充的程度。这张照片解释了吸收光谱的演变,并预测了一种奇特的同位素效应。

英文摘要:

Metallic nanoclusters displaying electronic shell structure exhibit the special feature of a correlation between their geometry and the number of delocalized electrons . Their shape evolution can be described as a quantum oscillation between quasi-resonant states (prolate and oblate configurations) whose amplitudes depend upon the degree of shell filling. The picture explains the evolution of absorption spectra and predicts a peculiar isotope effect .
