Sorry crackpot, there is no such thing as helium-2.
Well, it has a lifetime << 10^{-9} s, maybe 10^{-22} s or even less.
It surely is not stable.
Helium-2 may have been observed, according to several experiments done
in this century. But nobody has claimed certainty yet.
It's existence as a "resonance" is accepted. For one example,
see Wikipedia's page "Isotopes of helium".
