We report the stopping of a molecular oxygen beam, using a series of pulsed electromagnetic coils. A series of coils is fired in a timed sequence to bring the molecules to near rest, where they are detected with a quadrupole mass spectrometer. Applications to cold chemistry are discussed.

We report the stopping of an atomic beam, using a series of pulsed electromagnetic coils. We use a supersonic beam of metastable neon created in a gas discharge as a monochromatic source of paramagnetic atoms. A series of coils is fired in a timed sequence to bring the atoms to near-rest, where they are detected on a micro-channel plate. Applications to fundamental problems in physics and chemistry are discussed.
