Abstract
Using both the concepts of the polaron model of the electron‐excess color center and the valence‐electron model of atoms introduced in this paper, we have formulated a method to compute the optical absorption energy of an interstitial alkali‐earth cation contained in an alkali‐halide crystal. The numerical results are given for the interstitial ion Ca+ in KCl and KBr. The possibility of Kojima's model for the Z2 and Z3 bands is also discussed in this work.Keywords
