and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element. For example, most carbon (≈ 99 %) has 6 protons and 6 neutrons and is written ...

Stable isotopes are alternative forms of elements with different molecular weights that are found naturally and do not decay radioactively. Stable isotope analysis of elements such as carbon ...

The NASA/ESA Solar Orbiter recently recorded the highest-ever concentration of a rare helium isotope (3 He) emitted from the sun. A Southwest Research Institute-led team of scientists sought the ...

The CUBES-SIL lab has three magnetic sector, gas-source, isotope ratio mass spectrometers designed to measure the relative abundance of stable isotopes of light elements and molecules. These ...

This is precisely what the researchers have achieved. They were able to apply the method for the first time to a radioactive isotope for which there was a particularly accurate theoretical ...

This Section implements all activities of the IAEA's Water Resources Programme, which promotes and transfers know-how on the use of isotope hydrology as an effective tool for water resources ...

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 ...
