grasp is a software package in Fortran 95, adapted to run in parallel under MPI, for research
in atomic physics. The basic premise is that, given a wave function, any observed atomic …

Over the past decade, experimental microscopy and spectroscopy have made significant
progress in the study of the morphological, optical, electronic and transport properties of …

We report results for the computation of relativistic effects in quantum many-body systems
using quantum annealers. An average accuracy of 98.9% in the fine-structure splitting of …

The atomic mass of uranium-238 has been determined to be 238.050 787 618 (15) u,
improving the literature uncertainty by two orders of magnitude. It is obtained from a …

Recent advances in high-precision spectroscopy of highly charged ions necessitate an
understanding of energy shifts of ionic levels caused by external electric and magnetic …

As the most abundant element in the universe after hydrogen and helium, oxygen plays a
key role in planetary, stellar, and galactic astrophysics. Its abundance is especially …

This table is an updated compilation of experimental values of the magnetic hyperfine
anomaly in atomic and ionic systems. The literature search covers the period up to …

Context. It is now well established that the neutron star (NS) merger is at the origin of the
production of trans-iron heavy elements in the universe. These elements are therefore …

Characteristic x-ray spectra offer insight into the structure and composition of atoms and
molecules at a fundamental level where discrepancies in asymmetry, peak energy, and …

Here, the novel technique of extended-range high-energy-resolution fluorescence detection
(XR-HERFD) has successfully observed the n= 2 satellite in manganese to a high accuracy …
