Multistage Zeeman deceleration of NH X Σ − 3 radicals

摘要: We report on the Zeeman deceleration of ground-state NH radicals, using a decelerator that consists 100 pulsed solenoids and permanent hexapoles. Packets state-selected $(X\phantom{\rule{0.16em}{0ex}}^{3}\mathrm{\ensuremath{\Sigma}}^{\ensuremath{-}},N=0,J=1)$ radicals are produced with final velocities ranging between 510 150 m/s. The velocity distributions packets exiting probed map imaging detection. present $1+{2}^{\ensuremath{'}}$ resonance-enhanced multiphoton ionization scheme for allows detection under ion recoil-free conditions. Zeeman-decelerated in combination scheme, offer interesting prospects use this important radical high-resolution crossed-beam-scattering experiments.
