This research project continues on a joint experimental and theoretical research program that will address addresses important questions in the areas of high-resolution molecular spectroscopy, atomic collision physics, and molecular photodissociation. Spectroscopic studies of heteronuclear alkalki molecules, NaK, LiCs, NaCs, and RbCs, will measure vibrational, rotational, fine, and hyperfine structures of triplet states close to the dissociation limit, from which fundamental molecular interactions can be inferred. The project will also develop a technique using molecular photodissociation to produce fast, excited atoms whose kinetic energy and internal state can be precisely controlled. Using these velocity selected atoms, energy-pooling, associative ionization, and other reactions that provide stringent tests of atomic collision theory will be measured. On the broader impact of the program, the studies of LiCs, NaCs, and RbCs are of wide interest because these molecules have been proposed for use in quantum computing schemes using ultracold dipolar molecules. The experimental results will test the quality of theoretical potentials and the understanding of small interactions in small molecules. A further and significant broader impact of the program involves student training both for graduate students and undergraduates.

该研究项目继续进行联合实验和理论研究计划，将解决高分辨率分子光谱学，原子碰撞物理学和分子光解离领域的重要问题。光谱研究的heterobacterialalkki分子，钠钾，锂，钠铯，和RbCs，将测量振动，旋转，精细，超精细结构的三重态接近解离极限，从基本的分子相互作用可以推断。 该项目还将开发一种利用分子光解产生快速激发原子的技术，这些原子的动能和内部状态可以精确控制。 使用这些速度选定的原子，能量池，缔合电离，和其他反应，提供严格的测试原子碰撞理论将被测量。 在该计划的更广泛影响方面，LiCs，NaCs和RbCs的研究引起了广泛的兴趣，因为这些分子已被提议用于使用超冷偶极分子的量子计算方案。 实验结果将检验理论势能的质量和对小分子中小相互作用的理解。 该计划的进一步和更广泛的影响涉及研究生和本科生的学生培训。
