This project focuses on the investigation of cold atomic and molecular ion-atom collision processes in a hybrid neutral atom-ion trap. Recently developed techniques of laser cooling, trapping, and manipulation of cold neutral atoms will be used to make a refrigerator for the sympathetic cooling of an overlapping sample of atomic or molecular ions to very low temperatures. Various aspects of the collision process will be examined, such as resonant and near-resonant electron transfer, the elastic Langevin cross section, and potential quantum effects on the scattering.

本项目主要研究中性原子-离子混合阱中冷原子和分子离子-原子碰撞过程。最近发展的激光冷却、捕获和操纵冷中性原子的技术将用于制造一种冰箱，用于将原子或分子离子的重叠样品同步冷却到极低的温度。碰撞过程的各个方面将被检查，如共振和近共振电子转移，弹性朗之万横截面，和散射的潜在量子效应。
