Abstract
We identify laser-accessible transitions in group 16-like highly charged ions as candidates for high-accuracy optical clocks, including S-, Se-, and Te-like systems. For this class of ions, the ground 3PJ fi ne structure manifold exhibits irregular (nonmonotonic in J) energy ordering for large enough ionization degree. We consider the 3P2->3P0 (ground to fi rst-excited state) electric quadrupole transition, performing relativistic many-body calculations of several atomic properties important for optical clock development. All ions discussed are suitable for production in small-scale ion sources and lend themselves to sympathetic cooling and quantum-logic readout with singly charged ions.Citation
