摘要：

The absorption energy of the F‐centre in all 20 alkali halides are calculated in a pseudopotential theory developed by Bartram, Stoneham, and Gash, using a point‐ion lattice with an ion‐size correction. Polariztion and lattice distortion effects are included. Different anlaytical forms for the trial pseudo‐wave functions are investigated. It is found that the empirical reduction factor, introduced by Bartram, Stoneham, and Gash depends strongly on the type of wave function used. Copyright © 1979 WILEY‐VCH Verlag GmbH & Co. KGaA
