Characteristic energy losses of injected low energy electrons in ionic solids

Abstract

Characteristic energy losses of 0–18 V electrons have been measured for thin films of alkali and alkaline earth fluorides as well as NaBr, RbBr and RbCl. In addition to losses in the optical region there are also several losses at lower energy for each system, some of which may be due to triplet exciton states. Results for the fluorides, in particular, can be correlated with each other and with optical data.
