摘要：

Optical absorption bands produced by deformation of single crystals of CaO and SrO are presented. These bands, which occur on the shoulder of the fundamental absorption edge appear to arise from a vacancy complex with 〈100〉 symmetry. It is suggested that the absorption arises from excitons peturbed by an anion-cation vacancy pair. © 1969.
