Higher-order binding corrections to the Lamb shift of 2P states
U. D. Jentschura, K. Pachucki
We present an improved calculation of higher-order corrections to the one-loop self energy of 2P states in hydrogen-like systems with small nuclear charge Z. The method is based on…
Resummation of the Divergent Perturbation Series for a Hydrogen Atom in an Electric Field
U. D. Jentschura
We consider the resummation of the perturbation series describing the energy displacement of a hydrogenic bound state in an electric field (known as the Stark effect or the LoSurdo…
Electron Self Energy for the K and L Shell at Low Nuclear Charge
U. D. Jentschura, P. J. Mohr, G. Soff
A nonperturbative numerical evaluation of the one-photon electron self energy for the K- and L-shell states of hydrogenlike ions with nuclear charge numbers Z=1 to 5 is described.…
Lamb Shift of 3P and 4P states and the determination of
U. D. Jentschura, G. Soff, P. J. Mohr
The fine structure interval of P states in hydrogenlike systems can be determined theoretically with high precision, because the energy levels of P states are only slightly influen…
Calculation of the Electron Self Energy for Low Nuclear Charge
U. D. Jentschura, P. J. Mohr, G. Soff
We present a nonperturbative numerical evaluation of the one-photon electron self energy for hydrogenlike ions with low nuclear charge numbers Z=1 to 5. Our calculation for the 1S…
