A proton’s valence quarks (blue, red, and green), quark-antiquark pairs, and gluons (springs). Scalar gluon activity (pink) extends beyond the electric charge radius (orange) that surrounds the ...
Researchers have reported new experimental results addressing the origin of rare proton-rich isotopes heavier than iron, ...
A schematic diagram of proton and neutron distributions for mirror nuclei argon-31 and aluminum-31. Left side is the weakly bound proton-rich nucleus argon-31, which is predicted to exhibit a ...
