Suppose a nucleus of "lead atom" is trapped from lead plasma. Now, Is an antiproton able to moves round the "lead nucleus" ? And then, If the antiproton moves round the nucleus, Can other electrons with the antiproton move round the nucleus to make a neutralized "exceptional atom" ?
I rather think the problem will be that, due to the mass of the antiprotion (almost 2,000 times that of an electron), the size of the "orbitals" it can occupy will bring it very close to the nucleus - and indeed in a state with zero angular momentum it could go right up to the nucleus. Then POP, you would have annihilation.
Thank you sir ! And only a question that if a nucleus is 2000 times massive than an antiproton so is it(antiproton) able to moves round the nucleus like an electron ?
As Origin says, it is not in fact possible it have a nucleus that massive. But even if it were, I suspect there would be a problem, because the ground state would still contain antiprotons in orbitals with zero angular momentum, like the s orbitals in a normal atoms. As I say, the antiproton in such an orbital would be able to go right up to the nucleus, at which point annihilation would presumably be expected.
In theory any two particles of opposite charge could orbit each other. At one time it was suggested that muons could be used to enhance nuclear fusion. In practice such exotics are too short lived to be useful (most of the time). A counter example is Neutrons which have an outer shell of negative charge that allows them to behave somewhat like electrons a provide data on molecular structure.
Don't know if it can be explained. http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.99.112001
