Laser Cooling and Hyperfine Measurements of Radium-225 Ions
Roy Ready, Haoran Li, Spencer Kofford +10
Ra ions (nuclear spin ) have transitions that are first-order insensitive to magnetic field noise, which is advantageous for optical clocks and quantum informati…

Laser cooling and trapping of Ra
M. Fan, Roy A. Ready, H. Li +7
We report laser cooling and trapping of Ra ions. This was realized via two-step photoionization loading of radium into an ion trap. A robust source for Ra atoms…
