My rudimentary guess is either due to the strong and/or weak forces combined with lack of orbital/shell velocity.
The antiproton is negative.
The protons with neutrons are collectively positive.
The orbital velocity of the antiproton is slower than that of an electron (being something like 180x more massive).
And along with above, the - and + charges attract strongly. So the antiproton orbit rapidly decays to the nucleus.
- ncmncm 5y agoNo. The anti-proton is 1836x as massive as an electron. This makes its wavelength very short, so its lowest orbit very close to the nucleus, close enough that it has non-negligible amplitude to interact directly with a nuclear proton. Also, its higher-orbital energy levels are very close to one another, so it is easy for it to spit out a very low-energy photon and drop to the next orbit down.
