T he atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to ...

Physicist John Wheeler was involved in much of this Earth-shattering work, such as understanding the structure of the atom, ...

The results were published in Physical Review Letters on November 27. The atomic nucleus is a quantum many-body system composed of protons and neutrons, typically exhibiting a size similar to that ...

Physicists at UCLA have taken a major step toward creating the most accurate clocks ever by using a thin film of thorium-229.

In 1909 he began experiments that were to change the face of physics. He discovered the atomic nucleus and developed a model of the atom that was similar to the solar system. Like planets ...

An element's atomic number defines it ... neutrons A = 64 Number of neutrons N = 64 - 30 = 34 Since this is a nucleus there are no electrons There are 30 protons and 34 neutrons.

Atomic clocks that excite the nucleus of thorium-229 embedded in a transparent crystal when hit by a laser beam could yield the most accurate measurements ever of time and gravity, and even ...

But this year, his team and two other groups managed to finally achieve what he and Tamm had proposed, generating the first tick of a clock based on tiny energy shifts inside an atomic nucleus.

Question: when is a strong force not a strong force? Answer: when it’s anywhere outside the atomic nucleus. That at least is the case with the strong nuclear force, one of four fundamental ...
