Experiments with ultra-cold neutrons are of special relevance for fundamental research in physics, particularly in the fields of cosmology and particle physics.

Researchers have measured ultra-cold neutron production in a new source that will provide the highest density of UCNs in the world. By Fall 2004, Los Alamos expects to complete the most intense ...

Using the other approach, in bottle experiments, ultra-cold neutrons are trapped and left to decay, and the remaining neutrons are counted after the experimental run is over — typically lasting ...

Research into fundamental constants of nature and the search for new particles will benefit from new production method for ultra-cold neutrons.

Experiments with ultra-cold neutrons are of special relevance for fundamental research in physics, particularly in the fields of cosmology and particle physics.

Modern experiments use what are known as “ultra-cold” neutrons. These have such a low energy that their de Broglie wavelength is much longer than the distance between atoms, allowing them to be ...

But a team reporting in Physical Review Letters says it has smashed the prior "ultra-cold" neutron record. Neutrons were discovered nearly a century ago, but still hold a few secrets.

But it is extremely difficult to make analogous observations in gravitational fields because the effect of gravity is negligible at the atomic scale. To overcome this problem, Nesvizhevsky and ...

At a handful of neutron facilities around the world, researchers are slowing down neutrons until they have lost most of their energy. Known as ultra-cold neutrons, they move no faster than you can ...

First evidence that ultra-cold neutrons interact with moving nano-sized particles provides a new tool for chemists, biologists and engineers.

Neutrons are particularly difficult to trap, as they have no electric charge. But a team reporting in Physical Review Letters says it has smashed the prior "ultra-cold" neutron record.
