muoniumn.

Brit.

/mjuːˈəʊnɪəm/, U.S.

/mjuˈoʊniəm/

Origin: Formed within English, by derivation. Etymons: muon n., -ium suffix.

Etymology: < muon n. + -ium suffix, after positronium n.; compare -onium comb. form². Compare slightly earlier neutronium n., nucleonium n.

Particle Physics.

A short-lived, electrically neutral system analogous to an atom, consisting of a positive muon bound to an electron.

muonium1957

1957 J. I. Friedman & V.L. Telegdi in Physical Rev. 105 1681/2 μ⁺ can form ‘muonium’, i.e. (μ⁺e⁻).

1960 Physical Rev. Lett. 5 63/1 Muonium..can be formed when a positive muon is slowed down in matter and captures an electron from an atom in the stopping material.

1978 Nature 23 Nov. 324/3 The use of muons in chemistry is striking..for opening up an entirely new field of study—muonium chemistry.

1995 Physical Rev. B. 51 14762/2 Our knowledge of neutral atomic hydrogen in semiconductors is based primarily on studies of muonium.
