Abstract
If one computes the optical absorption due to electrons in ionic solids and includes the interactions with the electronic polarization field a resonance in both epsilon 2 and Im 1/ epsilon beginning about an exciton energy above the absorption edge is predicted. This model is used to analyse the soft X ray spectrum of the lithium halides and in particular LiF where the experimental data are most complete.Keywords
