# Antimatter: Production, storage and gravity experiments

Prodution and storage of antimatter seems to be a hard task. The latter is of course because antimatter is annihilated when it makes contact with regular matter.

Still, wouldn't it be possible to create $$\overline{^3He}^-$$ ions and store these in a metal container which has a lot of negative charge? By evacuating all of the air from the container before storage, we would be able to keep the $$\overline{^3He}^-$$ ions from getting into contact with regular matter gas molecules or the walls of the container.

$$\overline{^3He}$$ can be created in high energy lead-lead collisions*. Wouldn't it be possible to ionize these and store them as described above?

If we could make and store $$\overline{^3He}^-$$ as described above, we would be able to preform gravity experiments given enough $$\overline{^3He}^-$$ ions to make up a gas large enough for experimentation.
