Abstract
Angle dependence of Mossbauer spectra parameters on angle δO between the ψ-rays wave vectork and the unit cellc-axis of single crystal YBa2(Cu0.98Fe0.02)3O7−y is studied at room temperature. The present results give more detailed information about the correct manner of spectra fitting and EFG tensor parameters in positions of Fe-atoms in 1-2-3 crystal matrix.
