Emulsion photo of decay of kaon into pions
Numéro d’image : 11518123
| The first observation of the decay of a kaon into 3 pions,recorded in special photographic emulsion by Cecil Powell's team at Bristol University in 1948. The kaon produces the dense track coming in from top right. It decays at A into 3 pions. One of the pions moves away slowly,leaving a dense track,& then interacts at B. The other 2 pions are faster & leave relatively faint tracks as they move off in opposite directions towards top right & bottom left. (The distance between A & B is 25 micrometres). The kaon was the first discovered member of the family of "strange" particles,which contain a strange quark | |
