简单金属团簇的离解、fragmentation和fission

Dissociation, fragmentation and fission of simple metal clusters

Constantine Yannouleas, Uzi Landman, Robert N. Barnett

摘要:

这一教学评论提出了壳修正方法(SCM)及其变体,适用于描述形状变形和电子壳效应,能量学和金属团簇碎裂过程的衰变途径(例如,单体/二聚体解离和分裂)。的实验趋势进行比较的理论SCM的解释,此外裂变的第一性原理分子动力学模拟的理论结果进行了讨论。一些最新的见解有关的电子熵和有限温度效应的重要性给予特别关注。

英文摘要:

This pedagogical review presents the Shell Correction Method (SCM) and variants thereof, appropriate for describing shape deformations and electronic shell effects, energetics and decay pathways of metal-cluster fragmentation processes (e.g., monomer/dimer dissociation and fission). The experimental trends are compared to the theoretical SCM interpretations, and in addition theoretical results for fission from first-principles molecular-dynamics simulations are discussed. Some latest insights concerning the importance of electronic-entropy and finite-temperature effects are given special attention.
