A precision measurement of the proton’s weak charge narrows the search for new physics.
A re-analysis of data suggests that proton-neutron pairs in a nucleus may explain why their quarks have lower average momenta than predicted.
Inside every proton in every atom in the universe is a pressure cooker environment that surpasses the atom-crushing heart of a neutron star. That
Storing extremely slow neutrons in a novel trap enables precise measurement of a basic property of particle physics.
New method produces high-purity zirconium-89, a diagnostic radionuclide used to image cancerous tumors.
Yes. Such condensates, analogous to those in carbon-12, in heavier nuclei could change how we describe certain elements.
Mercury is a toxic element that occurs naturally and as an anthropogenic pollutant in the environment. The neurotoxin monomethylmercury (MMHg) is a
Particle collisions at RHIC free quarks and gluons from their confinement within ordinary particles (e.g., protons and neutrons) so
In semi-overlapping gold-gold collisions at RHIC, more particles emerge from the “equator” than perpendicular to the collision
Astatine-211 is produced by alpha beam irradiation of bismuth target material. The University of Washington has one of only a few cyclotrons in the
