Measurements on neutron-rich nuclei help to refine models of how heavy elements came into existence Models for how heavy elements are produced within stars have become more accurate thanks to ...

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 ...

WE have used the 110-in. Harwell cyclotron 1 as a source of high-energy neutrons for total cross-section measurements in good geometry. An internal beryllium target 8.9 mm. thick was bombarded by ...

New research has enhanced scientists' understanding of how free neutrons decay into other particles. The work provides the first measurement of the energy spectrum of the photons that are released in ...

Elements that do not exist in nature—that have been created in a laboratory—are unstable. After hours or days of one element bombarding another with enough energy for both to fuse, the resulting new ...

Understanding the origin of heavy elements on the periodic table is one of the most challenging open problems in all of physics. In the search for conditions suitable for these elements via ...

Finding fakes Illustration of how neutrons can pass easily through the metallic regions of an old coin, but are blocked by hydrogen-bearing compounds formed by corrosion. (Courtesy: S Kelley/NIST) The ...

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 ...
