All-Order Wichmann and Kroll Contribution in Heavy Electronic and Exotic Atoms
Jonas Sommerfeldt, Paul Indelicato
We present a theoretical study of the Wichmann and Kroll correction to the one-loop vacuum polarization (VP) to all-orders in . We consider electronic, muonic, and antiprotoni…

Precision Test of Bound-State QED at Intermediate-Z with Kaonic Neon
S. Manti, F. Sgaramella, L. Abbene +40
We report Dirac-Fock calculations of transition energies for kaonic neon (KNe). For the most intense line, the 7-6 transition, the calculated energy is 9450.28 eV, which includes a…

Towards Precision Spectroscopy of Antiprotonic Atoms for Probing Strong-field QED
Gonçalo Baptista, Shikha Rathi, Michael Roosa +26
PAX (antiProtonic Atom X-ray spectroscopy) is a new experiment with the aim to test strong-field quantum electrodynamics (QED) effects by performing high-precision x-ray spectrosco…
