Abstract
In a proof-of-principle experiment, we show that the longitudinal velocity of a supersonic beam of nitrogen atoms in the metastable 2D state can be decreased from 460 to 410 m s−1 using a 12-stage Zeeman decelerator. The experimental results are in good agreement with three-dimensional numerical particle trajectory simulations. The generation of velocity-tunable supersonic beams of metastable nitrogen atoms opens new avenues for the study of chemical reactions at millikelvin temperatures.
