Alpha particles are He\high{2+} (helium nucleus)
not to be confused with He\low{2} (helium molecules)
that DO exist but are unstable and only last 13 seconds or so.
Someone needs to fix the wiki... (done!)
\lohi[left]{}{4}He is a boson; \lohi[left]{}{3} is a fermion.
By the way, \lohi[left]{2}{4}He is somewhat a tautology, like all such
isotopic nomenclature, as He ALWAYS has an atomic number of 2,
otherwise it is not He (and U ALWAYS has an atomic number of 92,
otherwise it is no longer U).
