Einsteinium-255, produced through irradiation in ILL’s high-flux reactor, provided a continuous supply of fermium-255, ...

Because of their weight, interactions involving W bosons typically happen within the radius of a single proton or neutron ... or the inside of an unstable atomic nucleus (nuclear decay). This is lucky ...

That’s a tenth the radius of a small atom, but about a thousand times the size of an atomic nucleus. Nevertheless, that’s still a great deal smaller than the top end of previous studies ...

The approach, called the Beryllium Electron capture in Superconducting Tunnel junctions experiment (BeEST) works because the neutrino and the lithium nucleus are entangled, so that measurements of ...

The radius of an electron is approximately ... is the total number of protons and neutrons in the nucleus. It is measured in the atomic mass units (amu). Structure of an atom.

The nucleus, whose boundary is highlighted in semi-transparent ... showing the interior of the virion colour-coded by radius as from key. The white arrowhead marks the membrane bilayer, while the red ...
