“…However, there are some examples that demonstrate how the technical challenges associated with working with transplutonium elements can be overcome, even for less accessible elements such as Es. Highlights from the few previous Es studies include establishing nuclear properties from Es isotopes 6 , purifying Es from neighbouring actinides [7][8][9] , and initial reporting of various ionization potentials and thermodynamic properties of Es 1,10 . A few simple inorganic compounds-oxides and halides-of Es have been prepared.…”

General ConsiderationsCaution: 254 Es (t 1/2 = 275.7 days, 70.9 TBq g −1 ) and 249 Cf (t 1/2 = 351 years, 150 GBq g −1 ) are highly radioactive, and decay to α-, β-and γ-emitting isotopes. These isotopes and their decay daughters present substantial health risks, and were manipulated only in facilities specifically designed for the safe handling of long-lived radioactive materials. All measurements were taken in controlled facilities and/or using multiple containment procedures.

Highly charged ions: Optical clocks and applications in fundamental physics

et al. 2018

Recent developments in frequency metrology and optical clocks have been based on electronic transitions in atoms and singly charged ions as references. The control over all relevant degrees of freedom in these atoms has enabled relative frequency uncertainties at a level of a few parts in 10 −18 . This accomplishment not only allows for extremely accurate time and frequency measurements, but also to probe our understanding of fundamental physics, such as a possible variation of fundamental constants, a violation of the local Lorentz invariance, and the existence of forces beyond the Standard Model of Physics. In addition, novel clocks are driving the development of sophisticated technical applications. Crucial for applications of clocks in fundamental physics are a high sensitivity to effects beyond the Standard Model and Einstein's Theory of Relativity and a small frequency uncertainty of the clock. Highly charged ions offer both. They have been proposed as highly accurate clocks, since they possess optical transitions which can be extremely narrow and less sensitive to external perturbations compared to current atomic clock species. The large selection of highly charged ions in different charge states offers narrow transitions that are among the most sensitive ones for a change in the finestructure constant and the electron-to-proton mass ratio, as well as other new physics effects. Recent experimental advances in trapping and sympathetic cooling of highly charged ions will in the future enable advanced quantum logic techniques for controlling motional and internal degrees of freedom and thus enable high accuracy optical spectroscopy. Theoretical progress in calculating the properties of selected highly charged ions has allowed the evaluation of systematic shifts and the prediction of the sensitivity to the "new physics" effects. New theoretical challenges and opportunities emerge from relativistic, quantum electrodynamics, and nuclear size contributions that become comparable with interelectronic correlations. This article reviews the current status of theory and experiment in the field, addresses specific electronic configurations and systems which show the most promising properties for research, their potential limitations, and the techniques for their study.
