Accurate NMR shielding constants for arsenic (As) and antimony (Sb) in the AsF$_6^{-}$, AsO$_4^{3-}$, SbCl$_6^{-}$, and SbF$_6^{-}$ complexes were calculated using both non-relativistic coupled cluster methods and relativistic four-component density functional theory (DFT). The magnetic dipole moments of the $^{75}$As, $^{121}$Sb, and $^{123}$Sb nuclei were redetermined, leading to revised...

Laser resonance ionization spectroscopy in the ion source coupled directly to the isotope production target has been proven to be a highly sensitive tool for nuclear structure investigations on isotopes with low production and extraction yields [1]. While the efficiency of this technique is unrivalled, the spectral resolution is ultimately limited by Doppler broadening. At the ion source...

Theoretical models often invoke triaxial nuclear shapes to explain elusive collective phenomena, but such assumptions are usually difficult to confirm experimentally. The only direct measurements of the nuclear axial asymmetry $\gamma$ is based on rotational invariants of zero-coupled products of the electric-quadrupole (E2) operator, which generally require knowledge of a large number of E2...

One of the major scientific interests in the behaviour of He in diamond is due to the belief that the amount of $^{4}$He and the $^{3}$He /$^{4}$He ratio found within the material or its inclusions can be used to date terrestrial diamonds [1,2] or learn about the origins of meteoritic nanodiamonds [3]. Recently, He implantation has also been found to create colour centers in diamond that act...

It is still under intensive discussion, how magnetoelectric coupling actually occurs at the atomic scale in multiferroic (BiFeO3 or BFO). Nuclear solid-state techniques monitor local fields at the atomic scale. Using such an approach, we show that, contrary to our own expectation, ferroelectric and magnetic ordering in BFO decouple at the unit-cell level. Time differential perturbed angular...
