On a étudié les transitions 1s-3d dans le spectre d'absorption K du fer dans des monocristaux de Fe2O3. Au moyen de rayonnement X polarisé rectilignement et des règles de sélection correspondante on vérifie le caractère dipolaire des transitions. On vérifie le caractère dipolaire des transitions. On explique le mécanisme de mélange des orbitales 3d et 4p par le champ crystallin.1s-3d transitions in K-absorption spectra of Fe in Fe2O3 single crystals have been investigated. By means of linearly polarized X-radiation and corresponding selection rules the dipole character of transitions is verified. Mixing mechanism of 3d- and 4p-orbitals via crystalline fields is explained
