Zeeman deceleration of electron-impact-excited metastable helium atoms
New Journal of Physics, 2015 We present experimental results that demonstrate—for the first time—the Zeeman deceleration of helium atoms in the metastable 2 ^3 S _1 state. A more than 40% decrease of the kinetic energy of the beam is achieved for deceleration from 490 m s ^−1 to a ...

Multistage Zeeman deceleration of metastable neon [PDF]
The Journal of Chemical Physics, 2011 A supersonic beam of metastable neon atoms has been decelerated by exploiting the interaction between the magnetic moment of the atoms and time-dependent inhomogeneous magnetic fields in a multistage Zeeman decelerator.

Multistage Zeeman deceleration of atomic and molecular oxygen [PDF]
Physical Review A, 2018 Multistage Zeeman deceleration is a technique used to reduce the velocity of neutral molecules with a magnetic dipole moment. Here we present a Zeeman decelerator that consists of 100 solenoids and 100 magnetic hexapoles, that is based on a short ...

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. In order to maximize the number of particles that are successfully decelerated to a selected final velocity, we seek to optimize the phase-space ...

Low-Energy Collisions of Zeeman-Decelerated NH Radicals with He Atoms. [PDF]
J Phys Chem A, 2023 We report an experimental study of state-to-state inelastic scattering of NH (X 3Σ-, N = 0, j = 1) radicals with He atoms. Using a crossed molecular beam apparatus that combines a Zeeman decelerator and velocity map imaging, we study both integral and differential cross sections in the N = 0, j = 1 → N = 2, j = 3 inelastic channel. We developed various

High-Resolution Imaging of C + He Collisions using Zeeman Deceleration and Vacuum-Ultraviolet Detection. [PDF]
J Phys Chem Lett, 2021 High-resolution measurements of angular scattering distributions provide a sensitive test for theoretical descriptions of collision processes. Crossed beam experiments employing a decelerator and velocity map imaging have proven successful to probe collision cross sections with extraordinary resolution.

Zeeman deceleration beyond periodic phase space stability
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 ...
