Rezumat:

Mossbauer absorbtion spectra of 57Fe-doped NaCl crystal were measured and correlated with an adequateelectric field gradient computation to describe the dipolar complexes occurring at decay of Suzuki-phase under thermal treatment and X-ray irradiation. An electrostatic potential of the type Vi=Sum(qij/rij+lamdaij*exp(-rij/roij)) was taken into account in the evaluation of EFG tensor.
