DIFFUSION AND MOBILITY IN ALKALI HALIDES IN THE EXTRINSIC REGION

To sum up, one can say that for the 0;-center just as for the transition metal ions the crystal field splittings, the EPR linewidth (caused by unresolved hyperfine

The raman active fundamental mode of the XJ molécule (X~ : halogen ion) induces the inelastic light scattering, as is seen by comparison with calculated data on the free

A rough estimate of the corresponding diffusion length L and the average distance of the traps A$ (figure 5) can be made from Xb- 2L= 2 x 2(Dltb)'/' where D l is the dif-

L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des

Nous avons employe une approximation, celle du cr potentiel coherent n, pour construire une equation de transport auto-coherente, et nous avons calcult la

Taking into account the deforn~ation of tlie C r , ions by excited states admixed by the cubic lattice poten- tial the anisotropic slif interaction with nearest

- It is now well established that excitons in alkali Iialides (AH) created optically or by electron irradiation, undergo relaxation (self- trapping) and many of

Now, to determine the narrow and broad components, one has of course to measure the whole angular correlation curve and as this takes at least 20 h, the results
