    "abstract": "Complete vacuum polarization calculations incorporating finite nuclear size\nare presented for hydrogenic ions with principal quantum numbers n=1-5.\nLithiumlike, sodiumlike, and copperlike ions are also treated starting with\nKohn-Sham potentials, and including first-order screening corrections. In both\ncases dominant Uehling terms are calculated with high accuracy, and smaller\nWichmann- Kroll terms are obtained using numerical electron Green\u0027s functions.",
