摘要

穆斯堡尔二次多普勒能移（SODS）是原子热运动的一种相对论效应，它是穆斯堡尔参数之一。研究吸收体的SODS随温度的变化，可得到其同质异能移

和德拜温度

。本文描述了在德拜模型近似下，计算SODS的原理和方法；并用该方法计算了

-Fe样品的德拜温度

及在每一测温点下的SODS；还把计算结果与文献值及

Fe二次多普勒能移的理论值作了比较，进行了分析和讨论。

Abstract

The Mössbauer second-order Doppler shift (SODS) is a relativistic effect of thermal motion of atoms. It is one of the Mössbauer parameters. The isomer shift

and Debye temperature

can be obtained by means of studying the dependence of the SODS on temperature of the absorber.

The principle and method of evaluating the SODS are described by using the Debye model in this paper. Debye temperature

and the SODS at each measuring temperature for

-Fe sample have been calculated. The results are compared with the values reported in literatures and the theoretical values of the SODS for

Fe.
