“…Optical pumping of H‐like ions with circularly polarized light was proposed to produce polarization of both ionic nuclei and electronic shells. [ 78 ] While the first optical‐pumping experiments were performed for low‐ Z systems, no ion polarization has as yet been achieved in the high‐ Z domain. The schemes for production and implementation of spin‐polarized ions at the GF are currently under discussion.…”

The Gamma Factory initiative proposes to develop novel research tools at CERN by producing, accelerating, and storing highly relativistic, partially stripped ion beams in the SPS and LHC storage rings. By exciting the electronic degrees of freedom of the stored ions with lasers, high-energy narrow-band photon beams will be produced by properly collimating the secondary radiation that is peaked in the direction of ions' propagation. Their intensities, up to 10 17 photons per second, will be several orders of magnitude higher than those of the presently operating light sources in the particularly interesting-ray energy domain reaching up to 400 MeV. This article reviews opportunities that may be afforded by utilizing the primary beams for spectroscopy of partially stripped ions circulating in the storage ring, as well as the atomic-physics opportunities made possible by the use of the secondary high-energy photon beams. The Gamma Factory will enable groundbreaking experiments in spectroscopy and novel ways of testing fundamental symmetries of nature.

“…Hyperfine spectroscopy is very important tool in study of atomic and nuclear physics, especially which can be used to check fundamental interaction [1,2,3,4,5] such as electromagnetic and electroweak interaction with high accuracy, determine nuclear properties [6,7,8,9,10], develop atomic clock [11,12,13,14,15], and so on. Recently one kind of hyperfine transitions, which is known as hyperfine induced transition or hyperfine quenching, attracts more attention owing to analyzing spectra [16], determining isotopic ratios in stellar and diagnosing low-density plasma [17,18] besides those reasons mentioned above.…”

Interference effects in hyperfine induced AbstractThe hyperfine induced 2s2p 3 P 0 , 3 P 2 → 2s 2 1 S 0 E1 transition probabilities of Be-like ions were calculated using grasp2K based on multi-configuration Dirac-Fock method and HFST packages. It was found that the hyperfine quenching rates are strongly affected by the interference for low-Z Be-like ions, especially for 2s2p 3 P 0 → 2s 2 1 S 0 transition. In particular, the trends of interference effects with atomic number Z in such two transitions are not monotone. The strongest interference effect occurs near Z = 7 for 2s2p 3 P 0 → 2s 2 1 S 0 E1 transition, and near Z = 9 for 2s2p 3 P 2 → 2s 2 1 S 0 E1 transition.

“…A number of theoretical studies were reported recently on the spin-diagnostics of heavy, highly-charged ions at storage rings. For example, Bondarevskaya and co-workers [7] have proposed using the dependence of the hyperfine quenching (HFQ) on the polarization of the ion placed in an external magnetic field. The information on the population of the hyperfine substates |FM F ⟩ can be obtained also from the analysis of the linear polarization of x-rays emitted in hyperfinequenched characteristic transitions [8].…”

A review is presented of recent theoretical progress in atomic physics studies with spin-polarized heavy ions. Special emphasis is placed on the diagnostics of ion beams at storage rings. In particular, we show how the radiative electron capture from low-Z target atoms may serve as a very sensitive probe of heavy-ion spin polarization. The role of the electron-electron interactions in such a polarization-measurement method is discussed in detail.
