A Study of Charged Rare Gas Clusters

该项目涉及稀有气体小团簇的研究 原子;最重要的是，他集群。 “种子电荷” 一种产生Ar、Kr和Ne团簇的“膨胀”方法， 用于研究“幻数”或高度结构化的物质 这种方法产生的光谱，而一个单独的He集群 源开发。 He团簇的结构和动力学将被研究（一次 产生）作为液滴中原子数量的函数。 利用液滴中离子的介电共振， 液滴半径对质量的依赖性和耗散 将研究液滴的行为。 这些数据将提供 关于He团簇超流开始的信息 微观尺寸。

The project concerns the study of small clusters of rare gas atoms; most importantly, He clusters. The "charge seeded expansion" method of producing Ar, Kr and Ne clusters will be used to study the "magic numbers" or highly structured mass spectrum generated by this method, while a separate He cluster source is developed. The structure and dynamics of He clusters will be studied (once produced) as a function of the number of atoms in the droplet. Using the dielectric resonance of an ion in a liquid drop, the dependence of the drop radius on mass and the dissipative behavior of drops will be studied. These data will provide information concerning the onset of superfluidity in He clusters of microscopic size.
