We report precision measurements of the $^{20}\mathrm{Ne}$--$^{22}\mathrm{Ne}$ isotope shift for several transitions, as well as state-of-the-art, ab initio field-shift calculations. Our results are combined with historical measurements in a global fit to obtain the isotope shifts of all 50 low-lying neon levels with high precision. These level shifts show a wealth of electronic, nuclear, and relativistic phenomena. Relying on the analogy between mass shift and fine-structure operators, we… 

Nd+ isotope shift measurements in a cryogenically cooled neutral plasma

We report measurements of the isotope shifts of two transitions ($4{f}^{4}6s\ensuremath{\rightarrow}{[25044.7]}_{7/2}^{o}$ and $4{f}^{4}6s\ensuremath{\rightarrow}{[25138.6]}_{7/2}^{o}$) in neodymium

Direct Bound-Electron $g$ factor Difference Measurement with Coupled Ions

The quantum electrodynamic (QED) description of light-and-matter interaction is one of the most fundamental theories of physics and has been shown to be in excellent agreement with experimental

Probing new physics using Rydberg states of atomic hydrogen

We consider the role of high-lying Rydberg states of simple atomic systems such as $^1$H in setting constraints on physics beyond the Standard Model. We obtain highly accurate bound states energies

Spectroscopic tests for short-range modifications of Newtonian and post-Newtonian potentials

There are theoretical frameworks, such as the large extra dimension models, which predict the strengthening of the gravitational field in short distances. Here we obtain new empiric constraints for

Imaging Recoil Ions from Optical Collisions between Ultracold, Metastable Neon Isotopes.

An experimental scheme that combines the well-established method of velocity-map imaging with a cold trapped metastable neon target is presented, enabling opportunities for precision measurements in nuclear decays of cold, trapped, short-lived radioactive isotopes.

Decay microscope for trapped neon isotopes

We review the design, simulation, and tests, of a detection system for measuring the energy distribution of daughter nuclei recoiling from the beta-decay of laser trapped neon isotopes. This

Isotope Shifts in Atomic Spectra

Atomic and nuclear physics are two flourishing but distinct branches of physics; the subject of isotope shifts in atomic spectra is one of the few that links these two branches. It is a subject that

Isotope-shift calculations for atoms with one valence electron

This work presents a method for the ab initio calculation of isotope shift in atoms and ions with one valence electron above closed shells. As a zero approximation, we use relativistic Hartree-Fock

Hydrogen-deuterium isotope shift: From the 1S-2S-transition frequency to the proton-deuteron charge-radius difference

We analyze and review the theory of the hydrogen-deuterium isotope shift for the $1S$-$2S$ transition, which is one of the most accurately measured isotope shifts in any atomic system, in view of a

We critically examine the current status of theoretical calculations of the energies, the fine structure, and the isotope shift of the lowest-lying states of helium, searching for unresolved

Abstract—It has been revealed that the published results of measurements of the isotope shift of the ground state of even neon isotopes contain systematic errors. The errors are caused by the use of
