A Simple Method for Determining Center Shift and Spectral Area of a Mössbauer Spectrum
摘要：
一个非常简单的方法来确定中心（异构体）的位移，CS，和光谱面积，A，穆斯堡尔谱的概述。它的适用性证明在两个例子，即黄铁矿和三元σ相Fe-Cr-Ni化合物。用简单和标准的方法分析了前者在78-295 K温度区间和后者在78-295 K温度区间记录的谱组。用德拜模型分析了两种方法得到的CS（T）-和A（T）-数据。德拜温度的测定值在误差范围内彼此吻合良好，证明这种非常简单的方法适用于快速测定CS和A光谱参数。
英文摘要：
A very simple method for determining the center (isomer) shift, CS, and the spectral area, A, of a Mössbauer spectrum is outlined. Its applicability is demonstrated in two examples viz. pyrite and a ternary sigma-phase Fe-Cr-Ni compound. Sets of the spectra recorded in the temperature interval of 78-295 K for the former, and 78-295 K for the latter were analyzed with the simple and a standard method. CS(T)- and A(T)-data obtained with both ways of the spectra analysis were analyzed in terms of the Debye model. The determined values of the Debye temperatures agree well within the error limit with each other proving that this very simple method is suitable for a quick determining of CS and A spectral parameters.
