The work to be performed in this program is the spectroscopy of alkali clusters at the rotational level using resonant two-photon ionization and optical-optical double resonance spectroscopy. The goal of the experiments is to probe the dynamic behavior of the vibronic states through the influence of ro-vibronic coupling on the rotational levels. Clusters form the bridge between gas phase atomic physics and condensed matter physics, and the information which is sought at this detailed level is fundamental to understanding the transition from one phase to the next.

该程序要进行的工作是使用共振双光子电离和光学-光学双共振光谱法在旋转水平上对碱金属团簇进行光谱分析。 实验的目的是通过旋转振动耦合对旋转水平的影响来探测振动状态的动态行为。 团簇构成了气相原子物理学和凝聚态物理学之间的桥梁，在这个详细级别上寻求的信息对于理解从一个相到下一相的转变至关重要。
