Elusive Clock Transition in Strontium Revealed

Marric Stephens

Researchers have measured a hard-to-observe electronic transition in strontium that was predicted six decades ago. By Marric StephensO ptical atomic clocks rely on the existence of precisely defined, narrow-linewidth electronic transitions of atoms and ions.Currently, the most precise of these clocks uses the transition of strontium-87 from its ground state to its so-called 3 P 0 excited state (see Viewpoint: A Boost in Precision for Optical Atomic Clocks).Last year, Sebastian Blatt at the Max Planck Institute for Quantum Optics in Germany and his colleagues observed a similar transition in strontium-88.Now that same team has demonstrated coherent control of this transition, which involves strontium-88's ground and 3 P 2 excited states [1].The researchers say that, in addition to itsResearchers have measured a hard-to-observe electronic transition in strontium that was predicted six decades ago.
