Reference Quadrupole Moments of Transition Elements from Lamb Shifts in Muonic Atoms
S. Rathi, K. von Schoeler, P. Indelicato +1
We present a novel method for accurately measuring the absolute electric quadrupole moments of light transition elements . Our approach is based on performing…

Binding Energy of Muonic Beryllium: Perturbative versus All--Order Calculations
Shikha Rathi, Ulrich D. Jentschura, Paul Indelicato +1
We compute the ground-state binding energy of muonic Be in two ways: first, the fully perturbative treatment of the nuclear-size effect often employed in light systems, and sec…

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…
