We present an implementation of the nuclear spin-rotation (SR) constants based on the relativistic four-component Dirac-Coulomb Hamiltonian. This formalism has been implemented in the framework of the Hartree-Fock and Kohn-Sham theory, allowing assessment of both pure and hybrid exchange-correlation functionals. In the density-functional theory (DFT) implementation of the response equations, a ...
An attempt is made to improve the currently accepted muonic value for the 197Au nuclear quadrupole moment [+0.547(16)x10(-28) m2] for the 3/2+ nuclear ground state obtained by Powers et al. [Nucl. Phys. A230, 413 (1974)]. From both measured Mossbauer electric quadrupole splittings and solid-state density-functional calculations for a large number of gold compounds a nuclear quadrupole moment of...
Machine learning is employed to build an energy density functional for self-bound nuclear systems the first time. By kinetic as a of nucleon alone, robust and accurate orbital-free nuclei established. Self-consistent calculations that bypass Kohn-Sham equations provide ground-state densities, total energies, root-mean-square radii with high accuracy in comparison solutions. No existing theory c...
