It’s somewhat counterintuitive that ultracold neutrons are being used to help us understand how long neutrons lasted at the extraordinarily hot onset of the universe.

When radiochemist Jennifer Shusterman and her colleagues got the first results of their experiment, no one expected what they saw: Atoms of a weird version of the element zirconium had ...

Heavy duty A high-energy photonic jet (white and blue) blasts through a collapsing star with a black hole at its centre. The cocoon where free neutrons may be available for the r-process is shown in ...

Neutrons, the mundane-seeming inhabitants of atoms, could be hiding a secret connection to dark matter, according to a new proposal.

Neutrons produced from the fusion reactions create atomic cavities in the reactor’s wall materials, in which tritium can get trapped or permeate through if not recycled back to the plasma.

The Spallation Neutron Source fires beams of protons to a target filled with mercury, producing neutrons that are then directed to various research instruments.

With seven protons and two neutrons, the lopsided atomic nucleus of nitrogen-9 pushes the limits of what can even be considered a nucleus.

In the course of observations of the neutrons produced by the bombardment of elements with accelerated heavy hydrogen ions, we have noticed repeatedly the production of remarkably strong ionising ...
