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 ionization and recombination experiments with multiply charged ions relevant to astrophysical and fusion plasmas
Stefan Schippers
Past and ongoing research activities at the Heidelberg heavy-ion storage-ring TSR are reviewed which aim at providing accurate absolute rate coefficients and cross sections of atom…
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…
Dielectronic recombination of xenonlike tungsten ions
S. Schippers, D. Bernhardt, A. Müller +8
Dielectronic recombination (DR) of xenonlike W20+ forming W19+ has been studied experimentally at a heavy-ion storage-ring. A merged-beams method has been employed for obtaining ab…
