one orbits the other or vice versa? I would imagine both would orbit each other... - Omegatron 00:37, Jan 18, 2005 (UTC)
I understand it like this: forget about opbits. Particles do not literally orbit. A particle is really a quantum wavefuction, which has some (possibly zero) orbital momentum when it is a part of a system. So protonium is like hydrogen atom. In a ground state of H electron doesn't "orbit" anything (zero angular orbital momentum). In an excited state it usually has non-zero angular momentum.

"The other method involves putting antiprotons and positrons into the same magnetic cage." Shouldn't this be "antiprotons and protons"? Or am I missing something? RobertAustin 11:56, 20 October 2006 (UTC)Reply
