Abstract
The conditions which have to be fulfilled for accurate determination of the specific charge of the electron, by the Busch equation are discussed. It is shown that in the modern modification of the method, where a plane divergent electron beam is produced by a sinusoidal voltage applied to horizontal deflecting plates, these conditions are not fulfilled Theoretical allowance for non-fulfillment of these conditions can be made by replacing the lengthl in the Busch equation by a certain reduced length. The reduced length is found for the case of strictly parallel nonferromagnetic deflecting plates.
