In 1932, another British physicist, James Chadwick, discovered the neutron, another particle located within the nucleus. With the electron, proton, and neutron, scientists thought they had found ...

scientists discovered that some atomic nuclei—the center part of atoms, which make up all matter—were more stable than others. These nuclei had specific numbers of protons or neutrons ...

In 1919 Rutherford had discovered the 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 ...

For the first time, a research team has successfully produced one of the most neutron-rich isotopes, hydrogen-6, in an ...

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.

a proton in the lithium nucleus is resonantly excited by the interaction with the electron and promptly decays into a neutron and a positively charged pion. If this neutron subsequently transfers ...

In the world of nuclear physics, protons often ... collecting DVCS data on neutrons. The researchers thought they were ready to dig into their results—until they discovered an issue.

The strong force holds together quarks, the fundamental particles that make up the protons and neutrons of the atomic ... and independently David Politzer, discovered the key property of ...

The effects of the weak force were first discovered at the turn ... the decay doesn’t add up if you assume a neutron just decays to a proton and electron. He proposed that another particle ...
