Calculation of Radiative Corrections to E1 matrix elements in the Neutral Alkalis
J. Sapirstein, K. T. Cheng
Radiative corrections to E1 matrix elements for ns-np transitions in the alkali metal atoms lithium through francium are evaluated. They are found to be small for the lighter alkal…

Vacuum polarization calculations for hydrogenlike and alkalilike ions
J. Sapirstein, K. T. Cheng
Complete vacuum polarization calculations incorporating finite nuclear size are presented for hydrogenic ions with principal quantum numbers n=1-5. Lithiumlike, sodiumlike, and cop…
