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.]
