Isotope — Cet article possède des paronymes, voir : isotopie et isotrope. En physique nucléaire et en chimie, deux atomes sont dits isotopes si leur noyau a un nombre de protons identique mais un nombre de neutrons différent. Le nombre de protons dans … Wikipédia en Français
Pair-instability supernova — A pair instability supernova occurs when pair production, the production of free electrons and positrons in the collision between atomic nuclei and energetic gamma rays, reduces thermal pressure inside a supermassive star s core. This pressure… … Wikipedia

Cooper pair — In condensed matter physics, a Cooper pair or BCS pair is two electrons (or other fermions) that are bound together at low temperatures in a certain manner first described in 1956 by American physicist Leon Cooper.[1] Cooper showed that an… … Wikipedia
Magnetic Isotope Effect — Magnetic Isotope Effects arise when a chemical reaction involves spin selective processes, such as the Radical Pair Mechanism. The result is that some isotopes react preferentially, depending on their nuclear spin quantum number I. This is in… … Wikipedia

Transient equilibrium — In nuclear physics, transient equilibrium is a situation in which equilibrium is reached by a parent daughter radioactive isotope pair where the half life of the parent is slightly longer than the half life of the daughter. [… … Wikipedia
