Gamma ray becomes electron/positron pair
Bildnummer 11518105
| Cloud chamber photograph showing the conversion of a gamma ray into an electron-positron pair. Gamma rays do not leave tracks in a cloud chamber because they have no electric charge. But if they have enough energy,they can reveal themselves by converting into matter & antimatter,as in this case. Because they have opposite electric charge,the electron & positron curl away in opposite directions in the cloud chamber's magnetic field. Gamma rays are a very energetic form of light (electromagnetic radiation). They are also one of the 3 types of radiation emitted by radioactive materials. The photo was taken by French physicists Irene Curie & Frederic Joliot | |
