The central, relativistic Doppler and isomeric shifts of the emission Mossbauer spectra of ⁶⁷Cu(⁶⁷Zn) impurity atoms in the crystal lattices of sodium, potassium, rubidium and monovalent copper halides have been determined. A change in the electronic structure of impurity zinc atoms is demonstrated depending on the chemical nature of the atoms of the immediate environment and their coordination. Based on the comparison of experimental and calculated values of the quadrupole interaction constants for zinc impurity centers in alkali metal halides, it was concluded that the vacancy resulting from the substitution of alkali metal ions by zinc centers is located in the first coordination sphere of the cation sublattice. Keywords: alkali metal and copper halide crystals, impurity zinc atoms, Mossbauer spectroscopy.
