Dissociative Recombination of Rotationally Cold OH and Its Implications for the Cosmic Ray Ionization Rate in Diffuse Clouds

Ábel Kálosi, Lisa Gamer, Manfred Grieser +12

Observations of OH are used to infer the interstellar cosmic ray ionization rate in diffuse atomic clouds, thereby constraining the propagation of cosmic rays through and the s…

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,…

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…

Polarization-Dependent Disappearance of a Resonance Signal -- Indication for Optical Pumping in a Storage Ring?

W. Nörtershäuser, A. Surzhykov, R. Sánchez +10

We report on laser spectroscopic measurements on Li ions in the experimental storage ring ESR at the GSI Helmholtz Centre for Heavy Ion Research. Driving the $2s\,^3\!{S}_1\;(F…

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…
