Theoretical calculation of the electron-phonon coupling parameters of the F-centre in alkali halides
Description
The coupling parameters of the F-centre to lattice modes of cubic, tetragonal, and trigonal symmetry are calculated using the pseudopotential theory of Bartram, Stoneham, and Gash, for all 20 alkali-halides. Different analytical forms for the trial pseudo wave function are used. The results are compared with uniaxial stress and hydrostatic pressure experiments. General trends for the whole series of alkali-halides agree with experiments. (author)
