囚禁状态冷分子离子制备及应用

Generation and applications of cold and trapped molecular ions

  • 摘要: 冷分子离子,尤其是在离子阱中空间囚禁起来的冷分子离子具有空间定域、可长时间存储以及和与环境分离的特性。这些特性使得空间囚禁的冷分子离子在分子光谱精密测量、探测分子离子与中性分子之间的碰撞反应等方面越来越受到人们的重视,并在最近几年得到了快速的发展。文章介绍了冷分子离子的产生方法,及其近几年在精密测量和低温下的碰撞反应等研究领域取得的主要研究成果。

     

    Abstract: Cold molecular ions, especially those confined in ion traps, have novel properties such as high localization, long storage time and isolation from noisy environments. Because of this, spatially trapped cold molecular ions have attracted ever increasing attention as a promising candidate for precision molecular spectroscopy and fundamental studies of ionneutral collisions. The field of cold molecular ions has developed very fast in recent years. In this paper we will introduce the methods for generating cold and trapped molecular ions, and also the latest results of the applications of cold and trapped molecular ions in precision measurements and molecular collisions at very low temperatures.
