IT has been recently reported 1 that neutrons are liberated from beryllium by -rays of radium and that these are able to induce radioactivity in iodine. Following up this work, we have attempted to ...

THE ratio has been measured between the numbers of neutrons emitted from sources made by placing 300 mC. of radium–thorium in the centre of spheres of heavy water and beryllium respectively. These ...

Some atom-bomb secrets came out—or partly out—last week. During the Manhattan spy trial (see NATIONAL AFFAIRS), confessed spy David Greenglass, who worked as a machine-shop foreman at Los Alamos, ...

Researchers have observed a rare nuclear decay. Namely, the team measured low-kinetic-energy protons emitted after the beta decay of a neutron-rich nucleus beryllium-11. Researchers from the National ...

Scientists have uncovered an unexpected breakdown of nuclear order in a remarkably symmetric atom, challenging long-standing ideas about where such effects can occur.

So the Army has solicited interest from the nuclear community to find a means of affordably flinging high-flux beams of neutrons at these shells. In contrast to X-rays, neutrons zip through the walls ...
