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…
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,…
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…
The Cryogenic Storage Ring CSR
Robert von Hahn, Arno Becker, Felix Berg +41
An electrostatic cryogenic storage ring, CSR, for beams of anions and cations with up to 300 keV kinetic energy per unit charge has been designed, constructed and put into operatio…
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…
Visible line intensities of the triatomic hydrogen ion from experiment and theory
Annemieke Petrignani, Max H. Berg, Florian Grussie +7
The visible spectrum of H3+ is studied using high-sensitivity action spectroscopy in a cryogenic radiofrequency multipole trap. Advances are made to measure the weak ro-vibrational…
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…
