Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorized. The study, led by the ...

Nuclear physics is the study of the protons and neutrons at the centre of an atom and the interactions that hold them together in a space just a few femtometres (10-15 metres) across. Example ...

Nuclear physics research is focused on understanding the matter composed of quarks and gluons, which makes up 99% of the mass of the universe. Most of this matter is found at the core of atoms, the ...

Isolated in Sweden, she nevertheless continued to guide and interpret Hahn's work, ultimately realizing that his results represented the splitting of the atom—nuclear fission—in accordance ...
