Abstract

We report on the Zeeman deceleration of ground-state NH radicals, using a decelerator that consists of 100 pulsed solenoids and 100 permanent hexapoles. Packets of state-selected NH (XΣ3,N=0,J=1) radicals are produced with final velocities ranging between 510 and 150 m/s. The velocity distributions of the packets of NH exiting the Zeeman decelerator are probed using velocity map imaging detection. We present a 1+2 resonance-enhanced multiphoton ionization scheme for NH that allows for velocity map imaging detection under ion recoil-free conditions. The packets of Zeeman-decelerated NH radicals, in combination with the detection scheme, offer interesting prospects for the use of this important radical in high-resolution crossed-beam-scattering experiments.
