Electron-positron pair: matter/antimatter
Symmetrical production of matter & antimatter in two electron-positron pairs. In this bubble chamber photograph, two invisible gamma-ray photons enter from the top & each produce a pair of electrons & positrons (or anti-electrons). In the upper pair, the incoming photon also displaces an atomic electron, which shoots off towards bottom left. In the lower pair, all the photon's energy goes into the production of the electron & positron; being more energetic, this pair curves less in the bubble chamber's magnetic field than the upper pair, which form the characteristic spiral tracks of low-energy electrons & positrons.
