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…
Test of Time Dilation Using Stored Li+ Ions as Clocks at Relativistic Speed
Benjamin Botermann, Dennis Bing, Christopher Geppert +14
We present the concluding result from an Ives-Stilwell-type time dilation experiment using 7Li+ ions confined at a velocity of beta = v/c = 0.338 in the storage ring ESR at Darmsta…
Assignment of resonances in dissociative recombination of HD+ ions: high-resolution measurements compared with accurate computations
F. O. Waffeu Tamo, H. Buhr, O. Motapon +16
The collision-energy resolved rate coefficient for dissociative recombination of HD+ ions in the vibrational ground state is measured using the photocathode electron target at the…
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…
Evaporation of buffer gas-thermalized anions out of a multipole rf ion trap
J. Mikosch, U. Frühling, S. Trippel +3
We identify plain evaporation of ions as the fundamental loss mechanism out of a multipole ion trap. Using thermalized negative Cl- ions we find that the evaporative loss rate is p…
Dissociative recombination and low-energy inelastic electron collisions of the helium dimer ion
H. B. Pedersen, H. Buhr, S. Altevogt +10
This paper reports results from an experimental investigation of the dissociative recombination (DR) of the helium dimer ions at the heavy-ion Test Storage Ring (TSR) in Heidelberg…
Enhanced dielectronic recombination of lithium-like Ti19+ ions in external ExB fields
Timo Bartsch, Stefan Schippers, Michael Beutelspacher +9
Dielectronic recombination(DR) of lithium-like Ti19+(1s2 2s) ions via 2s->2p core excitations has been measured at the Heidelberg heavy ion storage ring TSR. We find that not only…
Dielectronic Recombination of Ground-State and Metastable Li+ Ions
A. A. Saghiri, J. Linkemann, M. Schmitt +10
Dielectronic recombination has been investigated for Delta-n = 1 resonances of ground-state Li+(1s^2) and for Delta-n = 0 resonances of metastable Li+(1s2s ^3S). The ground-state s…
