摘要: A theory of Vk centres in simple cubic Cs-halides the spirit Sewell's treatment small polaron is presented. The stability a hole trapped on single site and that centre are compared. Expressions for peak position width at half maximum uv (2Σ 2Σ) absorption band derived. results satisfactory agreement with experiment show interaction acoustic modes lattice vibrations becomes comparable to one optical modes, as mass halide increases. On presente une theorie du dans les halogenures de cesium structure CsCl, basee sur le modele petit Sewell. On obtient des expressions pour la et largeur mi-hauteur d'absorption l'ultraviolet 2Σ). Les resultats numeriques sont en accord satisfaisant avec l'experience montrent que l'interaction trou acoustiques cristal devient celle qu'il optiques lorsque l'on augmente l'ion halogene.
