The finding could be put to use at a new facility opening in 2020 that might create new elements—that is, nuclei with more than 118 protons—in addition to new isotopes of the known elements Scientists ...

All of us probably know what neutrons are, or have at least heard of them back in physics class. Yet these little bundles of quarks are much more than just filler inside an atom’s nucleus. In addition ...

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 shouldn’t be all that mysterious. Found inside every atomic nucleus, they may seem downright mundane—but they have long confounded physicists who try to measure how long these particles can ...

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 ...
