Abstract
ACCORDING to Landau and Rumer1 and others, the number of electrons of energy greater than E produced by one fast electron of energy E0 under a layer t cascade units thick is given by the formula, neglecting the collision loss and Compton effect: The integral is usually split into two terms containing the two exponentials, the first is evaluated by the saddle-point method and the second is neglected.
