Abstract

A simple approximation method is developed for calculating the quantum-mechanical transmission coefficient T( E) of a slow electron (in the energy range E < 20 eV) for the case of a one-dimensional surface potential barrier model which simulates most closely the real shape of the potential acting on an electron at a metal-vacuum interface. Although this method is developed for this particular case, it should permit, in principle, the direct investigation of arbitrary potential-energy functions.
