muonium Nuclear Physics.|mjuːˈəʊnɪəm|
[f. muon + -ium, after positronium.]
A short-lived neutral system, analogous to an atom, consisting of a (usu. positive) muon bound to an electron.
1957Friedman & Telegdi in Physical Rev. CV. 1681/2, µ+ can form ‘muonium’, i.e. (µ+e-). 1960Physical Rev. Lett. V. 63/1 The present Letter reports the formation of muonium in pure argon gas. Ibid., Muonium..can be formed when a positive muon is slowed down in matter and captures an electron from an atom in the stopping material. 1964S. DeBenedetti Nuclear Interactions viii. 593 The absence of muonium annihilation, despite the fact that both muons and electrons behave separately as simple Dirac particles, furnishes further evidence for the basic difference between electrons and muons. 1970G. K. Woodgate Elem. Atomic Struct. ii. 20 The equation therefore applies to all the hydrogenic atoms hydrogen, deuterium, tritium, muonium, positronium, etc. |
