“…The fine-structure splitting obtained by this procedure is given in Table 1 and is compared to former experimental and theoretical values. (10) The results of our analysis are in excellent agreement with the former experimental determination in [24] as well as the theoretical prediction by Yerokhin and coworkers [18,37]. It should be emphasized that the discrepancies with the theoretical predictions by Drake et al [39] were ascribed to higher-order effects in the mα expansion lacking in the NR-QED approach [24].…”

“…For a recent review on this topic, see [15]. Already for the two-electron system, the uncertainties of the nuclear level energies are larger than the nuclear finite size effect in these light systems, but substantial progress has been reported in recent years in the NR-QED treatment of helium and helium-like systems, as reported in [16][17][18].…”

Collinear laser spectroscopy in the 1s2s3S1→1s2p3P0,2 transitions of helium-like 11B3+ was performed using the HITRAP beamline at the GSI Helmholtz Centre. The ions were produced in an electron beam ion source, extracted, and accelerated to a beam energy of 4 keV/q. Results agree with previous measurements within uncertainty. Thus, it was demonstrated that the metastable state in He-like ions is sufficiently populated to carry out collinear laser spectroscopy. The measurement is a pilot experiment for a series of measurements that will be performed at a dedicated collinear laser spectroscopy setup at TU Darmstadt with light helium-like ions.

“…The intermediate region, Z ≈ 6 is particularly interesting, as both approaches have each maximum uncertainty. There is therefore an interest in studying QED for that light, but not too light, few-electron systems (see, e.g., [62][63][64] and the discussion therein).…”

Towards Precision Muonic X-ray Measurements of Charge Radii of Light Nuclei

We, the QUARTET Collaboration, propose an experiment to measure the nuclear charge radii of light elements with up to 20 times higher accuracy. These are essential both for understanding nuclear physics at low energies, and for experimental and theoretical applications in simple atomic systems. Such comparisons advance the understanding of bound-state quantum electrodynamics and are useful for searching for new physics beyond the Standard Model. The energy levels of muonic atoms are highly susceptible to nuclear structure, especially to the mean square charge radius. The radii of the lightest nuclei (with the atomic number, Z=1,2) have been determined with high accuracy using laser spectroscopy in muonic atoms, while those of medium mass and above were determined using X-ray spectroscopy with semiconductor detectors. In this communication, we present a new experiment, aiming to obtain precision measurements of the radii of light nuclei 3≤Z≤10 using single-photon energy measurements with cryogenic microcalorimeters; a quantum-sensing technology capable of high efficiency with outstanding resolution for low-energy X-rays.
