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 order to allow for the experimental observation of gravitational bound states, all interactions of the matter particles with other fields must be so small that their interference with the ...

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 ...

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 ...

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 ...

Many space-lovers know the phrase "We are all made of star stuff." And it's true - our planet formed from the dust cloud left over from the formation of our Sun, and from the planet, all life. That ...
