For example, a helium atom has an atomic mass of 4 ... there could be a particle with mass but no charge. He called it a neutron, and imagined it as a paired proton and electron.

Because the mass of a proton is equivalent to a neutron, the relative mass of an atom is the same as its nucleon (mass) number. Neutrons have no charge. Protons are positively charged. So the ...

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

In the first 10-14 seconds (give or take), the introduction of a slow-moving neutron forces the nucleus to bulge and ...

If we ascribe the ejection of the proton to a Compton recoil from a quantum of 52 × 10 6 electron volts, then the nitrogen recoil atom arising ... of the effects of a neutron in passing through ...

The new Neutron rocket includes a "hippo" mouth fairing that deploys upper stages by spitting them out from inside. The private space company Rocket Lab is on track to launch the first of its new ...

MIT research confirms neutron irradiation does not impact REBCO critical current, reducing risks in fusion plant designs and advancing energy initiatives.

On the neutron source front ... With BPA carrying only one boron atom per molecule, there is room to improve the cellular load by augmenting the number of atoms per boron drug molecule internalized.
