The quadrupole splitting value of pickling iron oxide is small, and the electric field symmetry around pickling iron oxide is good. 而进口、国产样品的穆斯堡尔谱的四极分裂(QS)都较小,表明酸洗氧化铁粉铁周围的电场对称性较好。
The calculated data of the quadrupole splitting and chemical isomer shift are in good agreement with those of experiments. Mossbauer谱四极矩分裂和化学位移计算值与实验结果符合很好。
The calculated mean quadrupole splitting 2 and the distribution widths σ△ characterize the symmetry and the similarity of Fe ion surroundings respectively and hence can be used as a measure of short range order in glasses. 所得到的平均四极裂距Δ和分布宽度σΔ分别对应于铁离子周围的环境对称性和位置相似性,从而用所得四极分裂(QS)分布可以量度玻璃中的短程有序。
The fitting of Mossbauer spectra according to Lorentzian curve in case of distribution of quadrupole splitting 在存在四极裂距分布情况下穆斯堡尔谱按洛伦兹曲线拟合的优度
