  • Abstract
    In secondary emission modelling programs, the total secondary emission yield is generally estimated using semi-empirical formulae proposed by Vaughan. The backscattered yield is often estimated simply as a constant fraction of the total yield, which is too simplistic, or by using a polynomial fit to the experimental data. The angular distribution of backscattered electrons on the energy and incident angle using the functional dependence.
