Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: apo me uye mp, zvichiteerana, masasi eiyo electron uye iyo positron (iyo yakafanana nekutsanangurwa seantiparticles).Saka, nokuda kwepositronium, kuderedzwa kwayo kunosiyana kubva kune electron nechinhu che 2. Ikoku kunoparira mwero wesimba kuvawo inenge hafu yeiyo iri nokuda kweatomu yehydrogen.  Mubvunzo: Nderipi rimwe zita rezvinhu zvinopesana nemhepo?
uwandu hweelectron nepositron
