Abstract
It is shown that a modified Doniach-Sunjic line shape, which simulates the results of recent calculations for a discrete model, yields a better fit to core-electron photoemission data from metals than the asymptotic power law. The new line-shape function may be expected to provide a good fit to data over an appreciable fraction of the width of the occupied conduction band provided there is no pronounced modulation in the density of states.Keywords
