Abstract
We discuss the response of a metal surface to an external electric field which varies slowly in space and time. An earlier calculation of the power absorption due to the creation of electron-hole pairs is improved with the inclusion of an interference term between ‘‘bulk’’ and ‘‘surface’’ excitation processes. With these improvements, we obtain excellent agreement with the measured inelastic-electron-scattering cross section for Cu(100).Keywords
