CONT

In the more distant future, extremely cold antiprotons should make it possible to produce and study antihydrogen, the antimatter atom formed by a positron in orbit around an antiproton. (Positrons, or antielectrons, are produced naturally in the radioactive decay of atomic nuclei.)

  • Physique atomique
CONT

L'antihydrogène est un atome constitué entièrement d'antiparticules : alors que l'hydrogène ordinaire se compose d'un proton positif et d'un électron négatif en orbite autour de ce proton, l'atome d'antihydrogène possède en son centre un «antiproton» négatif lié à un «positon» positif.

Spanish
