compton: size and shape of electrons 



of the size here assumed. Much the same effect, so far as the 

 scattering of 7-rays is concerned, results from the conception of 

 the electron as a ring of electricity of diameter comparable with 

 the wave-length of the incident beam. It has been shown by 



Fig. 3. Ratio of the intensity of the radiation scattered on the incident side 

 to that of the radiation scattered on the emergent side of a plate. The electron 

 is assumed to be a flexible sphere. • 



Davisson^^ and Webster^^^ that this conception is compatible 

 with the electromagnetic theory of the mass of the electron. I 

 have not as yet been able to solve completely the problem of the 

 scattering produced by such ring electrons. Approximate
