| Title | Williams, Evan James: certificate of election to the Royal Society |
| Description | Citation typed |
| Citation | Distinguished for both experimental and theoretical work on the passage of electrical particles through matter. His investigations of electron collisions showed the inapplicability of classical formulae and have helped to establish the correctness of quantal theory in this field. Experiments on photo-electric effect, on Compton effect, on scattering of hard gamma-rays and conservatism of energy in individual radiation processes have helped to verify the existing theory of radiation. He has obtained experimental evidence for the existence of the heavy electron. He has also helped to develop the theory of the effect of temperature on atomic arrangement in alloys. |
