An international team of scientists has shed light on the extreme ends of neutron and proton numbers. Their goal is to investigate the limits of the periodic table of chemical elements. How far can ...

For years, physicists have mapped the stability of atomic nuclei with remarkable confidence. The periodic table, with its neat rows and columns, hides a more chaotic reality underneath, where protons ...

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 ...

Crystallography is the science of analyzing the pattern produced by shining an X-ray beam through a material sample. A powder sample produces a different pattern than solid crystal. One longstanding ...

What is Atom Probe Tomography? Atom Probe Tomography (APT) is a powerful analytical technique that provides three-dimensional (3D) imaging and chemical composition analysis of materials at the atomic ...

Yuri Ralchenko led one of the oldest teams at the National Institute of Standards and Technology. The fate of some experiments hangs in the air. Lost Science Yuri Ralchenko led one of the oldest teams ...

One of the proud achievements of Oak Ridge National Laboratory is the discovery of three elements either by its own staff or in collaboration with other institutions in the United States and Russia.
