About anti-matter reactions

[joezavala]

Hey guys,

I was wondering, in theoratical terms, if lets say an anti-hydrogen partile would react with the hydrogen atoms in an h2o molecule, revealing the oxygen atoms as the outcome?

Thanks.

I'd imagine that the annihilation energy would at least ionise the oxygen, not sure what putting that much energy into an atom would do...

The antihydrogen has no reason to react with hydrogen rather than other particles. The antielectron would annihilate with some electron from the molecule (electrons don't belong to a specific atom, at least the valence electrons). Then, the antiproton may react with a proton in oxygen for instance.

 

The emitted gammas are not absorbed by the same atoms, with a high probability.
