摘要: Abstract The paramagnetic center of tetragonal symmetry formed by the Yb 3+ ion in KZnF 3 crystal has been studied using methods EPR, ENDOR and optical spectroscopy. location impurity structural model complex differing from KMgF have established. empirical scheme energy levels found. parameters its interaction with electrostatic field hyperfine ligands nearest environment determined. were used for analysis distortions lattice vicinity . transferred calculated distances between F − ions obtained taking into account found distortions. They are good agreement experimental values.
