论文摘要
对冷分子和超低原子之间相互作用的测量可以详细了解基本碰撞过程。可以使用各种实验几何形状进行这些测量，包括两个物种在梁中的位置，一个物种被困的地方或两种物种被困的时候。同时捕获的相互作用时间明显更长，并且对罕见碰撞事件的敏感性提高了。但是，将原子和分子系统相结合而存在着重大的实际挑战，这些挑战通常具有相互竞争的实验要求。在这里，我们详细描述了一个实验系统，该系统允许研究双重陷阱中超速原子和冷分子之间的冷碰撞，在该系统中，原子和分子分别使用静态磁和电场捕获了原子和分子。为了展示该系统功能，我们研究了氨（$^{14} $ nd $ _ {3} $和$^{15} $ nd $ _ {3} $）分子和rubidium（$^{87} $ rb and $^{85} $ rb）的少量碰撞。
Measurements of interactions between cold molecules and ultracold atoms can allow for a detailed understanding of fundamental collision processes. These measurements can be done using various experimental geometries including where both species are in a beam, where one species is trapped, or when both species are trapped. Simultaneous trapping offers significantly longer interaction times and an associated increased sensitivity to rare collision events. However, there are significant practical challenges associated with combining atom and molecule systems, which often have competing experimental requirements. Here, we describe in detail an experimental system that allows for studies of cold collisions between ultracold atoms and cold molecules in a dual trap, where the atoms and molecules are trapped using static magnetic and electric fields, respectively. As a demonstration of the system's capabilities, we study cold collisions between ammonia ($^{14}$ND$_{3}$ and $^{15}$ND$_{3}$) molecules and rubidium ($^{87}$Rb and $^{85}$Rb) atoms.
