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…
Absolute rate coefficients for photorecombination of berylliumlike and boronlike silicon ions
D. Bernhardt, A. Becker, C. Brandau +11
We report measured rate coefficients for electron-ion recombination for Si10+ forming Si9+ and for Si9+ forming Si8+, respectively. The measurements were performed using the electr…
Storage Ring Cross Section Measurements for Electron Impact Ionization of Fe 7+
M. Hahn, A. Becker, D. Bernhardt +10
We have measured electron impact ionization (EII) for Fe 7+ from the ionization threshold up to 1200 eV. The measurements were performed using the TSR heavy ion storage ring. The i…
Electron-ion Recombination of Fe XII forming Fe XI: Laboratory Measurements and Theoretical Calculations
O. Novotný, N. R. Badnell, D. Bernhardt +9
We have measured electron-ion recombination for Fe XII forming Fe XI using a merged beams configuration at the heavy-ion storage ring TSR located at the Max Planck Institute for Nu…
Storage-ring measurement of the hyperfine-induced 2s 2p 3P0 -> 2s2 1S0 transition rate in beryllium-like sulfur
S. Schippers, D. Bernhardt, A. Müller +8
The hyperfine induced 2s 2p 3P0 -> 2s2 1S0 transition rate in Be-like sulfur was measured by monitoring the decay of isotopically pure beams of 32-S12+ and 33-S12+ ions in a heavy-…
Storage Ring Cross Section Measurements for Electron Impact Ionization of Fe^11+ Forming Fe^12+ and Fe^13+
M. Hahn, D. Bernhardt, M. Grieser +8
We report ionization cross section measurements for electron impact single ionization (EISI) of Fe^11+$ forming Fe^12+ and electron impact double ionization (EIDI) of Fe^11+ formin…
Anisotropic fragmentation in low-energy dissociative recombination
S. Novotny, H. Rubinstein, H. Buhr +18
On a dense energy grid reaching up to 75 meV electron collision energy the fragmentation angle and the kinetic energy release of neutral dissociative recombination fragments have b…
Spectroscopy and dissociative recombination of the lowest rotational states of H3+
A. Petrignani, H. Kreckel, M. H. Berg +13
The dissociative recombination of the lowest rotational states of H3+ has been investigated at the storage ring TSR using a cryogenic 22-pole radiofrequency ion trap as injector. T…
