Abstract
The 7.6(5) eV nuclear magnetic-dipole transition in a single ion may provide the foundation for an optical clock of superb accuracy. A virtual clock transition composed of stretched states within the electronic ground level of both nuclear ground and isomeric manifolds is proposed. It is shown to offer unprecedented systematic shift suppression, allowing for clock performance with a total fractional inaccuracy approaching .
