Resolved-sideband laser cooling in a Penning trap

J. F. Goodwin, G. Stutter, R. C. Thompson +1

We report the laser cooling of a single $^{40} Ca^{+}$ ion in a Penning trap to the motional ground state in one dimension. Cooling is performed in the strong binding limit on…

Observation of the hyperfine transition in lithium-like Bismuth $^{209} Bi^{80 +}$ : Towards a test of QED in strong magnetic fields

Matthias Lochmann, Raphael Jöhren, Christopher Geppert +21

We performed a laser spectroscopic determination of the $2 s$ hyperfine splitting (HFS) of Li-like $^{209} Bi^{80 +}$ and repeated the measurement of the $1 s$ HFS of H-like $^{…
