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(…
Two-Loop Bethe Logarithms
Krzysztof Pachucki, Ulrich D. Jentschura
We calculate the two-loop Bethe logarithm correction to atomic energy levels in hydrogen-like systems. The two-loop Bethe logarithm is a low-energy quantum electrodynamic (QED) eff…
Two-Loop QED Bound-State Calculations and Squared Decay Rates
Ulrich D. Jentschura, Christoph H. Keitel, Krzysztof Pachucki
We discuss the epsilon-method as used in various recent QED bound-state calculations by considering mathematical model examples. Recently obtained results for higher-order self-ene…
Radiative Corrections to Parity Nonconserving Transitions in Atoms
J. Sapirstein, K. Pachucki, A. Veitia +1
The matrix element of a bound electron interacting with the nucleus through exchange of a Z boson is studied for the gauge invariant case of transitions in hydr…
