background: high density concrete is extensively used for efficient radiation attenuation in radiotherapy rooms and nuclear reactors. over the past eight years, some efficient galena-based concrete samples for shielding x or gamma rays was produced. the goal of this study was to produce a novel high density concrete against neutron and photon radiations using tourmaline and galena. materials an...

For the last two decades, experimental information on nuclear level densities for about 60 different nuclei has been obtained basis of Oslo method. While each these measurements typically compared to one or a few density models, global study including all missing. The present provides systematic comparison between data and six models 42 which $s$-wave resonance spacings are also available. We a...

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...
