Thanks for the explanation. It is all clear now. The point which made it clear is this:
When the antiproton approaches the exotic nuclei, the first thing it will do is to modify the nuclear dynamics
And concerning the CPT symmetry, I hope we are able to validate it. Also, can you tell me some of the other tests that are needed?
we need to check all the properties of matter and those of antimatter and check their match, and do that on various species of particles. we are far from there, as antimatter is not that easy to produce :)
