This research project focuses on a joint experimental and theoretical research program that will address important questions in the areas of atomic collision physics, molecular dissociation and high resolution molecular spectroscopy. Several collision processes will be investigated by developing a technique using molecular photodissociation to produce fast, excited atoms whose kinetic energy and internal state can be precisely controlled. Additional experiments will study the photodissociation process itself and will map out high-lying repulsive molecular potentials. Finally, a series of spectroscopic studies will probe high-lying triplet states of the alkali dimmer NaK. On the broader impact of the program, the experimental results will test the quality of theoretical potentials and the understanding of molecular interaction. In addition, education will play a major role in the research, with impact for both graduate and undergraduate students.

该研究项目的重点是一项联合实验和理论研究计划，该计划将解决原子碰撞物理、分子解离和高分辨率分子光谱学领域的重要问题。通过开发一种使用分子光解来产生动能和内态可以精确控制的快速、受激发的原子的技术，将研究几个碰撞过程。其他实验将研究光解过程本身，并将绘制出高位排斥分子势。最后，一系列的光谱研究将探索碱性二聚体NaK的高位三重态。就该计划的更广泛影响而言，实验结果将检验理论势能的质量和对分子相互作用的理解。此外，教育将在这项研究中发挥主要作用，对研究生和本科生都有影响。
