Radiative rotational lifetimes and state-resolved relative detachment cross sections from photodetachment thermometry of molecular anions in a cryogenic storage ring
C. Meyer, A. Becker, K. Blaum +23
Photodetachment thermometry on a beam of OH in a cryogenic storage ring cooled to below 10 K is carried out using two-dimensional, frequency and time dependent photodetachment…
Dissociative recombination measurements of NH using an ion storage ring
O. Novotný, M. Berg, D. Bing +12
We have investigated dissociative recombination (DR) of NH with electrons using a merged beams configuration at the TSR heavy-ion storage ring located at the Max Planck Institu…
Generation of neutral atomic beams utilizing photodetachment by high power diode laser stacks
A. P. O'Connor, H. Bruhns, F. Grussie +7
We demonstrate the use of high power diode laser stacks to photodetach fast hydrogen and carbon anions and produce ground term neutral atomic beams. We achieve photodetachment effi…
The Low-Temperature Nuclear Spin Equilibrium of H3+ in Collisions with H2
F. Grussie, M. H. Berg, K. N. Crabtree +5
Recent observations of H2 and H3+ in diffuse interstellar sightlines revealed a difference in the nuclear spin excitation temperatures of the two species. This discrepancy comes as…
