Fock-space relativistic coupled-cluster study of systematic shifts and fine-structure constant sensitivity in {\rm Cf}, {\rm Cm} and {\rm Bk} highly charged ions
Palki Gakkhar, D. Angom, B. K. Mani
Highly charged ions (HCIs) are among the most promising candidates proposed for the development of next-generation optical clocks and the precision tests of fundamental physics. In…
