Chronology of Milestone Events in Particle Physics

  Nobel prize to G. P. Thomson awarded in 1937 and to co-winner C. L. Davisson "for their experimental discovery of the diffraction of electrons by crystals''  


Thomson, G.P.;
Experiments on Diffraction of Cathode Rays
Proc. Roy. Soc. A117 (1928) 600;


1. Experiments are described giving the pattern formed by cathode rays scattered by thin films of aluminium, gold, celluloid, and an unknown substance.
2. These patterns are closely similar to those obtained with X rays in the "powder method.''
3. The sizes of patterns agree to 5 per cent with those predicted on the de Broglie theory of w ave mechanics, regarding the phenomenon as one of diffraction of the phase waves associated with the electrons.
