摘要：

A Mössbauer spectroscopic study has been made on x PbO · (1 - x) B2O3 containing 10 mol% Fe2O3 in melt before quenching. X has been varied between 0 and 0.85 in steps of 0.05. In samples with χ ≥ 0.25, a quadrupole doublet was observed. The corresponding isomershift and quadrupole spliting have shown a dependence on χ. A second type of spectrum has been observed in samples with χ < 0.25. It consisted of a six finger hyperfine pattern convulating over a central doublet spectrum. The corresponding internal field and the relative peak intensities are lower than observed in polycrystalline Fe2O3. The possible explanations for both types of spectrum are given. © 1979.
