Autodetachment of diatomic carbon anions from long-lived high-rotation quartet states
Viviane C. Schmidt, Roman Čurík, Milan Ončák +11
Highly excited C ions prominently feature electron detachment at a mean decay time near 3 milliseconds with hitherto unexplained origin. Considering various sources of un…
Unimolecular processes in diatomic carbon anions at high rotational excitation
Viviane C. Schmidt, Roman Čurík, Milan Ončák +11
On the millisecond to second time scale, stored beams of diatomic carbon anions C from a sputter ion source feature unimolecular decay of yet unexplained origin by electron…
Dissociative Recombination of Rotationally Cold OH and Its Implications for the Cosmic Ray Ionization Rate in Diffuse Clouds
Ábel Kálosi, Lisa Gamer, Manfred Grieser +12
Observations of OH are used to infer the interstellar cosmic ray ionization rate in diffuse atomic clouds, thereby constraining the propagation of cosmic rays through and the s…
Experimental determination of the dissociative recombination rate coefficient for rotationally-cold CH and its implications for the diffuse cloud chemistry
Daniel Paul, Manfred Grieser, Florian Grussie +13
Observations of CH are used to trace the physical properties of diffuse clouds, but this requires an accurate understanding of the underlying CH chemistry. Until this work,…
Laser-probing the rotational cooling of molecular ions by electron collisions
Ábel Kálosi, Manfred Grieser, Robert von Hahn +9
We present state-selected measurements of rotational cooling and excitation rates of CH molecular ions by inelastic electron collisions. The experiments are carried out at the…
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…
