Enhancing Divalent Optical Atomic Clocks with the ${}^1{\mathrm{S}}_0$$\leftrightarrow$${}^3{\mathrm{P}}_2$ Transition

Matthew A. Bohman, Sergey G. Porsev, David B. Hume +2

Divalent atoms and ions with a singlet $S$ ground state and triplet $P$ excited state form the basis of many high-precision optical atomic clocks. Along with the metastable $^{3}\m…
