Can an atomic nucleus contain both particles and antiparticles? [duplicate]
$begingroup$
This question already has an answer here:
What happens if we put together a proton and an antineutron?
2 answers
Is it theoretically possible to make a "deuterium" atom containing a proton and an antineutron in its nucleus?
Would the strong nuclear force cause attraction between a proton and an antineutron?
Would such a nucleus be stable, or would the proton somehow annihilate the antineutron when close enough?

Wikipedia has some info on annihilation reactions between nucleons & antinucleons, as I mention in this answer.

An antineutron ($bar{u}bar{d}bar{d}$) is made up of antiquarks and these will annihilate with the quarks in the proton ($uud$).
Such a nucleus is therefore unstable.

That does look like the most likely fate of such a system. The remaining $bar d$ and $u$ quarks would then likely form a $pi^+$ pion, which would eventually decay to an antimuon and then a positron.

N.B. from the links in the duplicates, it appears that there are short-lived $pbar{n}$ and $bar{p}n$ bound states, so the answer to "Would the strong force cause attraction ..." is yes.
