Abstract
The refractive indexes of CsCl, CsBr, and CsI show a strong nonlinear density dependence. This behaviour can be related to the closure of th e band gap by means of a constant-joint-density-of-states model for th e dielectric function. The results are discussed with respect to the d ielectric properties of other AB compounds.
