In the first direct probes of the core of the nuclear interaction, researchers find that leading theories on interactions between protons and neutrons describe them well, even in conditions where the protons and neutrons strongly overlap, such as in neutron stars
Nuclear physicists make new, high-precision measurement of the layer of neutrons that encompass the lead nucleus, revealing new information about neutron stars
A new theoretical model shows that alloying accelerator structures with oxygen provides a faster, better, cheaper path to predictable accelerator performance
