Аннотация:
The investigation of Er<sup>3+</sup> (4f<sup>11</sup>) ions in a KZnF<sub>3</sub> crystal is carried out by means of electron-nuclear double resonance. The parameters of the interaction of Er<sup>3+</sup> with F<sup>-</sup> ions of the nearest environment are determined. The microscopic calculation of these parameters is carried out. Also, the microscopic calculation of the pseudo-Zeeman interaction parameters is carried out for the first time.
