We studied the Mössbauer effect in 151Eu and 57Fe doped crystals in the search for laser-induced effects caused by changes in the hyperfine interaction due to electronic excitation. The Mössbauer spectra observed in the presence of laser radiation demonstrated a notable change of the shape of the 151Eu spectrum and the appearance of an additional hyperfine pattern in the case of the 57Fe Mössbauer resonance. © Nauka/Interperiodica 2007.
