As Helion is the nucleus of the rare, stable helium isotope 3 He called. A helion is a doubly positively charged cation and consists of two protons and one neutron . So it is the mirror core of the Triton .
The atomic nucleus of the other stable helium isotope, 4 He, is usually referred to as an alpha particle .
