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…
