2-Helium
2-Helium can't exist, since it lacks any neutrons to bind the one proton to the next one. Naturally protons can only be bound together without neutrons present through sheer force, since without neutrons present to forego the repelling force from each other they'd simply move away from each other, as soon as the force binding them disappears. Only under extreme pressure can they be forced together, where then if neutrons are present, they will attract it between their presences to enable fusion into a Helium. If two neutrons are present that would be stable 4-Helium. If protons are being forced together by gravity with any number of neutrons they'd fuse into Helium, same as the Sun. The fast moving of neutrons bound by gravity towards a gravity source would then colide releasing energy back as they'd fission again into protium, deuterium and tritium. One can only speak of a fusion binding where when the force exerted to keep them in place is removed and any time of it's existence remains thereafter. If that time equals zero, then there was never any fusion, and in the case of two protons never a 2-Helium.
