Kaufmann's Experiment and the Spinning Electron

Abstract

IN a paper in a recent number of the Zeitschr. für Physik, Wentzel has published a calculation of the X-ray screening constants on the basis of the spinning electron. He obtains values of the screening constants which are much larger than those experimentally determined, so raising a difficulty in the way of the acceptance of the spinning electron. Wentzel introduces into the calculations a force 1/c(µ[vX]) (µ= magnetic moment of spinning electron, v = velocity, X = electric field) the exact analogy of the force e[vH] on a moving electric charge in a magnetic field.
