Orders of Magnitude Improved Cyclotron-Mode Cooling for Non-Destructive Spin Quantum Transition Spectroscopy with Single Trapped Antiprotons

B. M. Latacz, M. Fleck, J. I. Jaeger +21

We demonstrate efficient sub-thermal cooling of the modified cyclotron mode of a single trapped antiproton and reach particle temperatures $T_{+} = E_{+} / k_{B}$ below $200$ mK in p…

Image-current mediated sympathetic laser cooling of a single proton in a Penning trap down to 170 mK axial temperature

C. Will, M. Wiesinger, P. Micke +22

We demonstrate a new temperature record for image-current mediated sympathetic cooling of a single proton in a cryogenic Penning trap by laser-cooled $^{9}$ Be $^{+}$ . An axial mode temp…

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…
