Do (or can) anti-protons form nuclei and has this ever been done. Does (or would) the strong nuclear force hold the anti-protons together?

A:
The answer is yes. Anti-deuterons, which consist of an anti-proton and an anti-neutron, were first observed in 1965 by a group from Columbia University. See:
http://prl.aps.org/abstract/PRL/v14/i24/p1003_1 . More recently both anti-helium
3 and anti-helium
4 have been observed.
