Laser-induced forced evaporative cooling of molecular anions below 4 Kelvin
Jonas Tauch, Saba Zia Hassan, Markus Noetzold +3
The study of cold and controlled molecular ions is pivotal for fundamental research in modern physics and chemistry. Investigations into cooling molecular anions, in particular, ha…
Quantum tunneling isotope exchange reaction H2 + D- -> HD + H-
Chi Hong Yuen, Mehdi Ayouz, Eric S. Endres +3
The tunneling reaction H + D HD + H was studied in a recent experimental work at low temperatures (10, 19, and 23~K) by Endres {\it et al.}, Phys. Rev. A…
Temperature-dependent rotationally inelastic collisions of OH- and He
Eric S. Endres, Steve Ndengue, Olga Lakhmanskaya +4
We have studied the fundamental rotational relaxation and excitation collision of OH- J=0 <-> 1 with helium at different collision energies. Using state-selected photodetachment in…
Incomplete rotational cooling in a 22-pole ion trap
E. S. Endres, G. Egger, S. Lee +3
Cryogenic 22-pole ion traps have found many applications in ion-molecule reaction kinetics and in high resolution molecular spectroscopy. For most of these applications it is impor…
Terahertz-visible two-photon rotational spectroscopy of cold OD-
Seunghyun Lee, Daniel Hauser, Olga Lakhmanskaya +5
We present a method to measure rotational transitions of molecular anions in the terahertz domain by sequential two-photon absorption. Ion excitation by bound-bound terahertz absor…
Sympathetic cooling of OH- ions using ultracold Rb atoms in a dark SPOT
H. López, B. Höltkemeier, J. Glässel +5
We are developing a new hybrid atom-ion trap to study the interaction of ultracold rubidium atoms with mass-selected OH- molecules. The ions are trapped inside an octupole rf-trap…
