The nuclear charge radius of ^{32}Si was determined using collinear laser spectroscopy. The experimental result was confronted with ab initio nuclear lattice effective field theory, valence-space in-medium similarity renormalization group, and mean field calculations, highlighting important achievements and challenges of modern many-body methods. The charge radius of ^{32}Si completes the radii of the mirror pair ^{32}Ar-^{32}Si, whose difference was correlated to the slope L of the symmetry energy in the nuclear equation of state.

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.

One of the most important properties influencing the chemical behavior of an element is the electron affinity (EA). Among the remaining elements with unknown EA is astatine, where one of its isotopes, At, is remarkably well suited for targeted radionuclide therapy of cancer. With the At anion being involved in many aspects of current astatine labeling protocols, the knowledge of the electron affinity of this element is of prime importance.

Article Synopsis
  • β-Nuclear magnetic resonance (NMR) spectroscopy is a highly sensitive technique that can analyze various elements and has been used successfully in nuclear and solid-state physics.
  • The research demonstrates the application of β-NMR for the first time in measuring NMR spectra of species in solution, focusing on (31)Mg ions in an ionic liquid.
  • Key findings include identifying specific resonances and showing that β-NMR could become a valuable technique in general chemistry and biochemistry.
