Cold reactive collisions

该奖项支持在接近绝对零度的温度下研究分子碰撞的实验研究。这种“超冷化学”对于理解化学反应背后的基本物理以及冷星际介质的化学非常重要。这项研究将使超冷原子物理学的精密工具能够应用于传统的化学反应。在这项工作中，分子和原子将被低温氦气冷却，它们的碰撞和化学反应将被激光光谱学研究。该计划的广泛影响包括培养研究生和本科生在冷分子研究和许多现代技术领域，如激光，光学，高真空和低温学。潜在的应用包括开发控制化学反应和化学合成的新方法，这是物理化学的长期目标。

This award supports experimental research investigating molecular collisions at temperatures close to absolute zero. This "ultracold chemistry" is important for understanding the fundamental physics underlying chemical reactions as well as the chemistry of the cold interstellar medium. The research will enable the delicate tools of ultracold atomic physics to be applied to traditional chemical reactions. In this work, molecules and atoms will be cooled by a cryogenic helium gas and their collisions and chemical reactions will be studied by laser spectroscopy.The broader impacts of this program include the training of graduate and undergraduate students in cold molecule research and many areas of modern technology, such as lasers, optics, high vacuum, and cryogenics. Potential applications include the development of new methods to control chemical reactions and chemical synthesis, a long- standing goal of physical chemistry.
