  • /ˈpɒz.ɪ.tɹɒn/ (UK)
  • /ˈpɑ.zɪ.tɹɑn/ (US)

Etymology

From positive + -tron (electron). Coined by American physicist Carl Anderson in 1932 to replace the earlier term antielectron.

Meanings

  1. (particle) The antimatter equivalent of an electron, having the same mass but a positive charge.
    • If these particles carry unit positive charge the curvatures and ionizations produced require the mass to be less than twenty times the electron mass. These particles will be called positrons. [1933 March 15, Carl D. Anderson, “The Positive Electron”, in Physical Review, volume 43:
    • The notion of a positron weapon remains the stuff of science fiction.
