Is there any way to stablize these particles?
What do you mean by stabilize? Positrons are stable by nature. As for any hypereon, muon, tau, or whatever, they all desintegrate sooner or later. Theoretically, we could make their lives as long as we wish if we could make them travel as near to speed 'c' as we'd like, but practically, we can only make them last a few times their usual lifetime.
