Helion (chemistry)

Helion

As a Helion, the nucleus of the stable helium isotope 3He is called. A Helion is a doubly positively charged cation, consisting of two protons and one neutron. Thus, it is the mirror nucleus of the Tritons.

3U plays an important role as intermediates in the proton-proton reaction by which hydrogen is converted into helium stars.

The nucleus of the helium other stable isotope 4He is usually referred to as alpha particles.
