A TEST FOR ELECTRON POLARIZATION 

 TABLE I 



475 



Bombarding Potential 77 volts, Azimuth angle d = 270 degrees. Ro = zero 

 reading of galvanometer, R = galvanometer reading. {R — Ro) = D = deflection, 

 D = arithmetic mean of deflections. \D — D\ = S = deviation from mean, 

 5 = mean deviation. 



Number of observations, N = 36; D ^ 3.104; 5 = 0.154 



Probable error, A = 0.845 -r^, ~ -^22 approx. 



.-. Deflection, D = 3.104 ± .022.
