Relativistic calculation of the two-photon decay rate of highly-excited ionic states
Ulrich D. Jentschura, Andrey Surzhykov
Based on quantum electrodynamics, we reexamine the two-photon decay of one-electron atoms. Special attention is paid to the calculation of the (two-photon) total decay rates which…
Two-Photon Decays Reexamined: Cascade Contributions and Gauge Invariance
Ulrich D. Jentschura
The purpose of this paper is to calculate the two-photon decay rate corresponding to the two-photon transitions nS->1S and nD->1S in hydrogenlike ions with a low nuclear charge num…
Isotope shift in the dielectronic recombination of three-electron ^{A}Nd^{57+}
C. Brandau, C. Kozhuharov, Z. Harman +25
Isotope shifts in dielectronic recombination spectra were studied for Li-like ^{A}Nd^{57+} ions with A=142 and A=150. From the displacement of resonance positions energy shifts δE^…
Photon angular distribution and nuclear-state alignment in nuclear excitation by electron capture
Adriana Pálffy, Zoltán Harman, Andrey Surzhykov +1
The alignment of nuclear states resonantly formed in nuclear excitation by electron capture (NEEC) is studied by means of a density matrix technique. The vibrational excitations of…
Self-energy values for P states in hydrogen and low-Z hydrogenlike ions
U. D. Jentschura, P. J. Mohr
We describe a nonperturbative (in Zalpha) numerical evaluation of the one-photon electron self energy for 3P_{1/2}, 3P_{3/2}, 4P_{1/2} and 4P_{3/2} states in hydrogenlike atomic sy…
Complete two-loop correction to the bound-electron g factor
Krzysztof Pachucki, Andrzej Czarnecki, Ulrich D. Jentschura +1
Within a systematic approach based on the dimensionally regularized nonrelativistic quantum electrodynamics, we derive the complete result for the two-loop correction to order $(α/…
