Splitting Isotope Shift in the $1s2p{}^3{P}_{0,1,2}$ Fine-Structure Triplet in ${}^{12,13,14}$C${}^{4+}$: Experiment and Theory

Patrick Müller, Kristian König, Emily Burbach +6

We report measurements and theoretical calculations of the fine-structure splittings in all three $1s2s{}^3{S}_1\to 1s2p{}^3{P}_{0,1,2}$ transitions in the heliumlike syst…
