The finding could be put to use at a new facility opening in 2020 that might create new elements—that is, nuclei with more than 118 protons—in addition to new isotopes of the known elements Scientists ...

An element's atomic number defines it. An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So ...

An international collaboration led by scientists from the University of Hong Kong, RIKEN (Japan), and CEA (France) have used the RI Beam Factory (RIBF) at the RIKEN Nishina Center for Accelerator-base ...

Large atomic nuclei, containing many protons and neutrons, tend to be unstable. But stable nuclei do exist, and can be seen as an 'island of stability' on a graph of proton number against neutron ...

The most feasible reaction is between the nuclei of two heavy isotopes of hydrogen – deuterium (D) and tritium (T). This needs robust and efficient 14.1 MeV neutron detectors for monitoring and ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Protons and neutrons are the heaviest particles in an atom and as a result they make up most of its mass. The mass of electrons is ...
