Abstract
Mössbauer emission spectra of57Co: LiTaO3 show as a consequence of the nuclear decay anomalous emission line intensities in the subspectra of Fe2+ and Fe3+. Magnetic field and angle dependence of Fe3+ intensities can be explained by taking into account polarization-and crystal-field effects in the excited states. The experimental results for LiTaO3 are in good agreement with theory and previous measurements on LiNbO3.
