The Raman spectra of the Ba1–xLaxF2+x solid solutions (0.005 ≦ x ≦ 0.31) are presented. The low‐frequency scattering is studied in some detail. The spectra indicate that no large clusters are present in solid solutions studied. A cross‐over which can be interpreted in terms of the fracton model is observed.
