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…

Radiative Corrections to One-Photon Decays of Hydrogenic Ions
J. Sapirstein, K. Pachucki, K. T. Cheng
Radiative corrections to the decay rate of n=2 states of hydrogenic ions are calculated. The transitions considered are the M1 decay of the 2s state to the ground state and the E1(…

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…
