[f. meso- + -tron.]
The name orig. given to the meson (meson3).
1938Anderson & Neddermeyer in Nature 12 Nov. 878/2 The existence of particles intermediate in mass between protons and electrons has been shown in experiments on the cosmic radiation... We should like to suggest..the word ‘mesotron’ (intermediate particle) as a name for the new particles. It appears quite likely that the appropriateness of this name will not be lost, whatever new facts concerning these particles may be learned in the future. 1939Ibid. 13 May 796/2 The meson or mesotron was first introduced by Yukawa to serve as the connecting link between β -ray disintegration and the forces responsible for nuclear binding. 1942Endeavour Jan. 22/2 Skobeltzyn..has argued against the theory of Heisenberg and Euler that the spontaneous disintegration of mesotrons is the mechanism responsible for the formation of the electronic component observed in the lower layers of the atmosphere. 1949Koestler Insight & Outlook x. 136 The so-called ‘elementary particles’—electrons, photons, neutrons, mesotrons, and so forth. |
