In 2010, for the first time, more than 100 new unstable isotopes — nuclides with different numbers of neutrons — were discovered in a single year (see 'The nuclide trail'). We expect more than ...

BEIJING -- Chinese researchers have synthesized two new nucleus isotopes that contain 84 neutrons and 82 neutrons, according to a recent research article published in the journal Physical Review ...

Starting from these stable isotopes, nuclei become increasingly unstable as neutrons are added or removed, until neutrons can no longer bind to the nucleus and "drip" out. This limit of existence ...

Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences and their collaborators have ...

Scientists and professionals in nuclear-related areas from all over the world can now use the IAEA Isotope Browser mobile application in all six official United ... The app provides the properties of ...

Provided by the International Atomic Energy Agency (IAEA), the Isotope Browser app is a useful chemistry resource that provides information on over 4,000 chemical isotopes (or “nuclides,” if ...

The nucleus of each atom contains protons and neutrons. 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 neutron separation energy tells how much energy is required to remove one neutron from the nucleus of a given isotopes. "It gives information on the structure of the nucleus and is an ...
