Display Chart N/Z (630 x 890 mm)

The purchase of an N/Z Diagram poster grants free access to its online version at www.plateformenum.jeulin.fr - Representation of the stability valley. - Color codes indicating stable nuclides and different types of radioactive nuclides. - Indication of the decay modes of unstable nuclides: α emissions, β+, β-, protons, neutrons. - N=Z line. - Graphical definitions of isotopic nuclei (same Z), isobars (same A), isotones (same N). - Indication of "magic numbers" (specific stabilities of nuclei with these numbers of neutrons or protons). - Aston curve: binding energy B per nucleon in MeV as a function of mass number A = N + Z. The position of the iron nucleus is indicated on the curve.
