%0 Journal Article %T Accurate evaluations of the field shift and lowest-order QED correction for the ground $1^1S-$states of some light two-electron ions %A Alexei M. Frolov %J Physics %D 2014 %I arXiv %R 10.1063/1.4895042 %X Mass-dependent and field shift components of the isotopic shift are determined to high accuracy for the ground $1^1S-$states of some light two-electron Li$^{+}$, Be$^{2+}$, B$^{3+}$ and C$^{4+}$ ions. To determine the field components of these isotopic shifts we apply the Racah-Rosental-Breit formula. We also determine the lowest order QED corrections to the isotopic shifts for each of these two-electron ions. %U http://arxiv.org/abs/1405.6409v3
