Collisions between ultracold atoms and cold molecules in a dual electrostatic-magnetic trap

摘要: Measurements of interactions between cold molecules and ultracold atoms can allow for a detailed understanding fundamental collision processes. These measurements be done using various experimental geometries including where both species are in beam, one is trapped, or when trapped. Simultaneous trapping offers significantly longer interaction times an associated increased sensitivity to rare events. However, there significant practical challenges with combining atom molecule systems, which often have competing requirements. Here, we describe detail system that allows studies collisions dual trap, the trapped static magnetic electric fields, respectively. As demonstration system's capabilities, study ammonia ($^{14}$ND$_{3}$ $^{15}$ND$_{3}$) rubidium ($^{87}$Rb $^{85}$Rb) atoms.
