Nonadiabatic transitions in electrostatically trapped ammonia molecules
Moritz Kirste, Boris Saratakov, Melanie Schnell +1
Nonadiabatic transitions are known to be major loss channels for atoms in magnetic traps, but have thus far not been experimentally reported upon for trapped molecules. We have obs…
Nature of Ar bonding to small Co_n^+ clusters and its effect on the structure determination by far-infrared absorption spectroscopy
Ralf Gehrke, Philipp Gruene, Andre Fielicke +2
Far-infrared vibrational spectroscopy by multiple photon dissociation has proven to be a very useful technique for the structural fingerprinting of small metal clusters. Contrary t…
Laser-induced alignment and orientation of quantum-state-selected large molecules
Lotte Holmegaard, Jens H. Nielsen, Iftach Nevo +4
A strong inhomogeneous static electric field is used to spatially disperse a supersonic beam of polar molecules, according to their quantum state. We show that the molecules residi…
Operation of a Stark decelerator with optimum acceptance
Ludwig Scharfenberg, Henrik Haak, Gerard Meijer +1
With a Stark decelerator, beams of neutral polar molecules can be accelerated, guided at a constant velocity, or decelerated. The effectiveness of this process is determined by the…
Stark deceleration of OH radicals in low-field-seeking and high-field-seeking quantum states
Kirstin Wohlfart, Frank Filsinger, Fabian Grätz +2
The Stark deceleration of OH radicals in both low-field-seeking and high-field-seeking levels of the rovibronic ground state is demonstrated using a single…
Quantum reflection of helium atom beams from a microstructured grating
Bum Suk Zhao, Stephan A. Schulz, Samuel A. Meek +2
We observe high-resolution diffraction patterns of a thermal-energy helium-atom beam reflected from a microstructured surface grating at grazing incidence. The grating consists of…
