In the world of nuclear physics, protons often take the spotlight. But now, for the first time, the neutron has stepped into it. A recent experiment using the U.S. Department of Energy’s Jefferson Lab ...

The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other.

He called it a neutron, and imagined it as a paired proton and electron. There was no evidence for any of these ideas. Chadwick kept the problem in the back of his mind while working on other things.

Quarks are the reason protons have a positive charge. Each quark has a fraction of an electric charge. A proton has two up ...

Protons and neutrons–known collectively ... "He developed a ML-based tool to discriminate fake signals from real neutrons, and this was vital to achieve our final results." ...

Beta decay involves the conversion of a down quark to an up quark. This changes a neutron into a proton plus an electron. The proton stays in the nucleus and the electron leaves the atom with high ...

In the first case, a neutron is converted to a proton and releases an electron and an anti-neutrino. In the second, a proton is converted to a neutron and releases a positron and a neutrino.

The emission of beta radiation provides evidence that neutrons and protons are made up of quarks. Beta (\(\beta^-\)) decay is the release of an electron by the change of a neutron to a proton.

He called it a neutron, and imagined it as a paired proton and electron. There was no evidence for any of these ideas. Chadwick kept the problem in the back of his mind while working on other things.

In the world of nuclear physics, protons ... neutron data. That’s when physicist Adam Hobart, a researcher at IJCLab, stepped in. He used machine learning to tell the difference between real ...
