Principles and Design of a Zeeman–Sisyphus Decelerator for Molecular Beams [PDF]
ChemPhysChem, 2016 We explore a technique for decelerating molecules using a static magnetic eld and optical pumping. Molecules travel through a spatially varying magnetic fi eld and are repeatedly pumped into a weak-field seeking state as they move towards each strong ...

Evolutionary Algorithm Optimization of Zeeman Deceleration: Is It Worthwhile for Longer Decelerators? [PDF]
J Phys Chem A, 2019 In Zeeman deceleration, only a small subset of low-field-seeking particles in the incoming beam possess initial velocities and positions that place them within the phase-space acceptance of the device.

A traveling wave Zeeman decelerator [PDF]
Journal of Physics: Conference Series, 2020 We developed a new-concept Zeeman decelerator which produces a traveling magnetic trap. Atoms and molecules possessing a magnetic dipole moment, in so-called low field seeking states, are trapped around a node of a propagating wave provided that the ...

Getting a grip on the transverse motion in a Zeeman decelerator [PDF]
Journal of Chemical Physics, 2014 Zeeman deceleration is an experimental technique in which inhomogeneous, time-dependent magnetic fields generated inside an array of solenoid coils are used to manipulate the velocity of a supersonic beam. A 12-stage Zeeman decelerator has been built and

Imaging Resonance Effects in C + H2 Collisions Using a Zeeman Decelerator. [PDF]
J Phys Chem Lett, 2023 International audienceAn intriguing phenomenon in molecular collisions is the occurrence of scattering resonances, which originate from bound and quasi-bound states supported by the interaction potential at low collision energies.

Zeeman deceleration beyond periodic phase space stability [PDF]
New Journal of Physics, 2017 In Zeeman deceleration, time-varying spatially inhomogeneous magnetic fields are used to create packets of translationally cold, quantum-state-selected paramagnetic particles with a tuneable forward velocity, which are ideal for cold reaction dynamics ...

Low-Energy Collisions of Zeeman-Decelerated NH Radicals with He Atoms. [PDF]
J Phys Chem A, 2023 International audienceWe report an experimental study of state-to-state inelastic scattering of NH (X 3 sigma-, N = 0, j = 1) radicals with He atoms. Using a crossed molecular beam apparatus that combines a Zeeman decelerator and velocity map imaging, we
