A Determination of the Masses and Velocities of Three Radium B Beta-Particles The Relativistic Mass of the Electron
Abstract
An accurate determination of the values of me and v of three Ra B β-particles was made by means of an electrostatic spectrograph. It is shown that these particles obey the Lorentz model for electrons rather than the Abraham model, for velocities as high as 0.75 of the velocity of light. The uncertainty in the experiment is less than one-tenth the magnitude of the difference between the two models.
