| الوصف: | Abstract Highly charged ions (HCIs) are less sensitive to external perturbations and are therefore attractive for the development of ultrastable clocks. However, only a few HCI candidates are known to provide optical clock transitions. In this work, we discover a large family of HCI clocks, with more than 100 suitable optical clock transitions hidden in the fine-structure terms of open-shell ions over 70 elements. Their projected instabilities and accuracies are $${\sigma }_{\tau } \sim 1{0}^{-17}/\sqrt{\tau }$$ σ τ ~ 1 0 − 17 / τ and δ ν/ν |
