Abstract
Width of Xray Spectrum Lines Due to Damping.—(1) Assuming exponential damping, the equation for the ether vibrations, y=ekt sin (pt+A), is developed as a Fourier integral and thus a theoretical relation of the width to the damping factor is found. If we define the width of the line as the range in wave-length throughout which the intensity is greater than half the maximum intensity of the line, then xλλ=dpp=2kp, very closely.
