We report on an experiment conducted at the ESR storage ring aiming at the study of the X-ray emission of $$\text {Xe}^{54+}$$ Xe 54 + ions colliding with Xe atoms at a beam energy of 50 MeV/u. The radiation resulting from the ion–atom interaction was observed using a high-resolution spectrometer based on metallic–magnetic calorimeter technology. In order to benchmark the capabilities of these detectors for high-precision atomic physics experiments, we identified several transitions from H-like and He-like xenon and determined their energies. Furthermore, the 1s-Lamb shift in $$\text {Xe}^{53+}$$ Xe 53 + was estimated using the measured line energies. The results are compared with previous experimental studies and theoretical predictions.

“…Heavy ion and atom encounters lead to the short-time formation of diatomic quasimolecules. Presently, collisions of highly charged ions with neutral atoms, e.g., Xe 54+ -Xe, are available for experimental investigation at the GSI Helmholtz Center for Heavy Ion Research [1][2][3][4][5]. The upcoming experiments at NICA [6], HIAF [7], and GSI/FAIR [8] will allow for an observation of heavy few-electron systems' collisions up to bare nuclei, such as U 92+ -U 92+ .…”

The rigorous two-center approach based on the dual-kinetically balanced finite-basis-set expansion is applied to one-electron, heteronuclear diatomic Bi-Au, U-Pb, and Cf-U quasimolecules. The obtained 1σ ground-state energies are compared with previous calculations, when possible. Upon analysis of three different placements of the coordinate system’s origin in the monopole approximation of the two-center potential: (1) in the middle, between the nuclei, (2) in the center of the heavy nucleus, and (3) in the center of the light nucleus, a substantial difference between the results is found. The leading contributions of one-electron quantum electrodynamics (self-energy and vacuum polarization) are evaluated within the monopole approximation as well.
