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…
Recombination of open-f-shell tungsten ions
Claude Krantz, Nigel R. Badnell, Alfred Müller +2
We review experimental and theoretical efforts aimed at a detailed understanding of the recombination of electrons with highly-charged tungsten ions characterised by an open 4f sub…
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…
Recombination of W18+ ions with electrons: Absolute rate coefficients from a storage-ring experiment and from theoretical calculations
K. Spruck, N. R. Badnell, C. Krantz +10
We present new experimentally measured and theoretically calculated rate coefficients for the electron-ion recombination of W([Kr] ) forming W. A…
Absolute rate coefficients for photorecombination and electron-impact ionization of magnesium-like iron ions from measurements at a heavy-ion storage ring
D. Bernhardt, A. Becker, M. Grieser +10
Rate coefficients for photorecombination (PR) and cross sections for electron-impact ionization (EII) of Fe forming Fe and Fe, respectively, have been measu…
