positron (plural positrons)

  1. (physics) The antimatter equivalent of an electron, having the same mass but a positive charge.
    The notion of a positron weapon remains the stuff of science fiction.
    • [1933 March 15, Carl D. Anderson, “The Positive Electron”, in Physical Review, volume 43:
      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.]
