The minerals beryl and emerald are beryllium silicates and were known to the ancient world; the emperor Nero used a large emerald the better to view gladiatorial fights in the area. Their beautiful ...

This limitation has been overcome for beryllium-9 by precisely determining ... use a comparison between measurements done on the same isotope, so that the nuclear structure is identical but ...

Nishiizumi and Caffee analyzed lunar soil for the presence of a radioactive form of the element beryllium called beryllium-10. Beryllium-10 is an isotope of beryllium; it contains four protons and six ...

While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element ...

Generally, the heavier elements have radioactive isotopes while the lighter elements are stable. There are exceptions to this rule though. Many isotopes are present for a very short time because of ...

Stable isotopes are non-radioactive forms of atoms. Although they do not emit radiation, their unique properties enable them to be used in a broad variety of applications, including water and soil ...

As soon as it was known 1 that the heavy isotope of hydrogen could be separated by electrolysis, experiments were started in this Laboratory to elucidate the mechanism of the separation.

the heavy hydrogen isotope tritium (3H or T); and the beryllium isotope beryllium-7 (7Be); but these unstable isotopes later decayed into 3He and 7Li, respectively, as above. Essentially all of the ...

In a recent paper in Nature Physics, an international research collaboration used world-class instrumentation at the Facility ...

The application of Stable Isotopes measurements can be used to integrate, indicate, record and trace fundamental ecological processes. Rapid technological advances over the past decade have greatly ...

Isotopes have different sets of properties. Their chemical properties do not vary while the physical properties may vary. Isotopes also exhibit different nuclear properties. Applications Based on ...

Earth’s magnetic field serves as a protective barrier against cosmic radiation from space. But this shield isn’t always as stable as it appears. There are some short-lived episodes when the ...
