Atomic particles

Usage examples of neutrons.

String theory adds the new microscopic layer of a vibrating loop to the previously known progression from atoms through protons, neutrons, electrons and quarks.

But in 1968 experimenters at the Stanford Linear Accelerator Center, making use of the increased capacity of technology to probe the microscopic depths of matter, found that protons and neutrons are not fundamental, either.

Far from being the most elementary material constituent, atoms consist of a nucleus, containing protons and neutrons, that is surrounded by a swarm of orbiting electrons.

The strong force, which keeps quarks locked up inside of protons and neutrons, arises from individual quarks exchanging gluons.

Dense with neutrons, the waste would merge with the unbreathable underMantle and, perhaps, sink at last into the Quantum Sea.

Baryons - protons and neutrons, the components of light, visible matter - and photinos - their dark matter analogues -existed largely independently of each other, interacting only through gravitational attraction.

His sense of time telescoped, so that he could watch the insect-like, fluttering decay of free neutrons - or step back and watch the grand, slow decomposition of protons themselves .
