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…

Associative detachment in anion-atom reactions involving a dipole-bound electron

Saba Zia Hassan, Jonas Tauch, Milaim Kas +5

Associative electronic detachment (AED) between anions and neutral atoms leads to the detachment of the anion's electron resulting in the formation of a neutral molecule. It plays…

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…
