Lifetimes of the Metastable and States of Ra
Haoran Li, Huaxu Dan, Mingyu Fan +9
We report lifetime measurements of the metastable and states of Ra. The measured lifetimes, …
Spectroscopy of electric dipole and quadrupole transitions in Ra
Spencer Kofford, Haoran Li, Robert Kwapisz +5
We report on spectroscopy of the low-lying electronic transitions in Ra. The ion's low charge to mass ratio and convenient wavelengths make Ra a promising o…
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…
