In this talk I will review latest activities in molecular approaches to physics beyond the standard model and discuss challenges and opportunities that laser spectroscopy of specifically tailored heavy molecules provides. I plan to discuss: Synthesis of molecules with shortlived isotopes from spallation sources, laser cooling of radioactive molecules, measurement of nuclear anapole moments and...
In this talk, we will discuss ab initio calculations of the nuclear chart and predictions for the drip lines from light through medium-mass nuclei. Starting from a chiral two- and three-nucleon interaction with good saturation properties, we have calculated ground-state and separation energies for all nuclei from helium to iron, nearly 700 in total. From a systematic comparison, we find that...
One modern approach to unravelling the complex nuclear many body problem has been to track the evolution of nuclear properties in systems ever closer to the proton or neutron drip-line. Binding energies are among the first observables reaching yet uncharted regions of the nuclear chart and their trends are sensitive to a wide range of nuclear-structure phenomena. As such, they provide...
The exotic isotopes in the Ca region ($Z = 20$) have attracted significant experimental and theoretical attention due to the proposed shell closures at neutron numbers $N = 32,34$ [1-5]. In particular, the subshell closure at $N=32$ represents a puzzling case, since the unexpectedly large charge radius of $^{52}$Ca [2] challenges the magicity of this isotope. The lack of a consistent...
Antimony (Sb) contains 51 protons, one proton above the magic Z = 50 proton shell closure. Therefore, its magnetic moments serve as an ideal candidate to probe the proton single particle behavior along the Sb isotopic chain, while its quadrupole moments shed light on collectivity and core polarization effects as a function of neutron number towards the shell closure at N = 82. Furthermore,...
As a result of our continuing quest to apply β-NMR to biomolecular and chemical studies, we report here the measurement of the magnetic moment of 26Na with a few ppm precision. This also led to an improved precision on the magnetic moments of 27-30Na. This achievement was made possible by the previously reported 2018 upgrades to the β-NMR setup [IsoWork18], which resulted in an improvement in...
