Helion (chemistry)

Helion (chemistry)

A helion is a short name for the naked nucleus of Helium, a doubly positively charged "helium ion". In practice, "helion" refers to the stable helium-3 nucleus, in opposition to the other stable nucleus helium-4, which is usually referred to as an alpha particle. The (helium-3) helion consists of two protons and one neutron.

According to CODATA, the mass of a helion particle is 5.006 412 14(86) × 10-27 kg.
