The constants of the superhyperfine interaction of Gd3+ with the 19F nuclear spins in the first four coordination shells were determined from the ENDOR spectra of a trigonal BaF2: Gd3+ center. These data were used for analysis of the crystalline latt

A computer simulation of lattice distortions around an impurity ion Eu2+ in MeF2 fluorites (Me=Ca, Sr, Ba) is reported. ENDOR data on displacements of F− ions distant from an impurity center were used to determine the parameters of the Eu2+-F− sh
