“…Most of the spectroscopic data that we have on nuclear moments comes from the measurement of the hyperfine splitting of atomic lines (Yang et al, 2022). These measurements performed over long isotopic chains can set stringent tests on different nuclear models (Garcia Ruiz et al, 2016;de Groote et al, 2020;Vernon et al, 2022).…”

Molecules containing short-lived, radioactive nuclei are uniquely positioned to enable a wide range of scientific discoveries in the areas of fundamental symmetries, astrophysics, nuclear structure, and chemistry. Recent advances in the ability to create, cool, and control complex molecules down to the quantum level, along with recent and upcoming advances in radioactive species production at several facilities around the world, create a compelling opportunity to coordinate and combine these efforts to bring precision measurement and control to molecules containing extreme nuclei. In this manuscript, we review the scientific case for studying radioactive molecules, discuss recent atomic, molecular, nuclear, astrophysical, and chemical advances which provide the foundation for their study, describe the facilities where these species are and will be produced, and provide an outlook for the future of this nascent field.

“…The relativistic electronic structure calculations were performed using the locally modified versions of dirac [37,38], mrcc [39][40][41] and Exp-T [42,43] codes. Note, that the nuclear structure effects such as the nuclear deformation and polarization [1,62,63] can lead to additional terms in Eq. ( 1).…”

“…Changes in mean-square (ms) charge radii can be extracted from the isotope shift (IS) of the atomic transitions. Isotope shift is represented as a sum of two contributions: field shift (FS), which is associated with a change in the nucleus charge distribution, and the mass shift (MS), connected with the nuclear recoil effect [1]. The mass shift contribution can be further separated into the normal mass shift (NMS) and specific mass shift (SMS).…”

Electronic factors for the field and mass isotope shifts in the 6p 2 P 3/2 → 7s 2 S 1/2 (535 nm), 6p 2 P 1/2 → 6d 2 D 3/2 (277 nm) and 6p 2 P 1/2 → 7s 2 S 1/2 (378 nm) transitions in the neutral thallium were calculated within the high-order relativistic coupled cluster approach. These factors were used to reinterpret previous experimental isotope shift measurements in terms of charge radii of a wide range of Tl isotopes. Good agreement between theoretical and experimental King-plot parameters was found for the 6p 2 P 3/2 → 7s 2 S 1/2 and 6p 2 P 1/2 → 6d 2 D 3/2 transitions. It was shown that the value of the specific mass shift factor for the 6p 2 P 3/2 → 7s 2 S 1/2 transition is not negligible compared to the value of normal mass shift in contrary to what had been suggested previously. Theoretical uncertainties in mean square charge radii were estimated. They were substantially reduced compared to the previously ascribed ones and amounted to less than 2.6%. The achieved accuracy paves the way to a more reliable comparison of the charge radii trends in the lead region.

Tunable single‐frequency lasers are the most prominent tool for high‐resolution spectroscopy, allowing for the study and exploitation of the electronic structure of atoms. A significant milestone relies on the demonstration of integrated laser technology for performing such a task. The device presented here is composed of a compact Fabry–Perot monolithic resonator capable of producing tunable and Fourier‐limited nanosecond pulses with a MHz‐class frequency stability without active cavity stabilization elements. It also has the remarkable capability of exploiting the Raman effect to funnel efficiently the broad spectrum of an input laser to a spectrally‐bright Stokes pulse at hard‐to‐access wavelength ranges. The targeted atom for the demonstrations is 152Sm, released as an atomic vapor in a hot cavity environment. Here, the Stokes field is tuned to a wavelength of 433.9 nm, while a crossed‐beams spectroscopy setup is used to minimize the Doppler broadened spectral features of the atoms. With this work, the suitability of integrated diamond Raman lasers as a high‐resolution in‐source spectroscopy tool is demonstrated, enabling many applications in atomic and nuclear physics. The integrated form‐factor and inherent simplicity makes such a laser an interesting prospect for quantum‐technology based sensing systems and related applications.
