Comparison of the Mössbauer Effect to Time-Differential Perturbed Angular Correlations: The Case of Fe57 in a Nickel Host

  • C. Hohenemser
Conference paper


Time-differential perturbed angular correlations (TDPAC) is a technique which, when applied to hyperfine interactions in solids, has yielded information similar to the Mössbauer effect. Until our recent experiment on the Fe57/Ni impurity-host system, no one had studied any system by TDPAC that had also been studied in detail by the Mössbauer effect. Our TDPAC experiment on Fe57/Ni was made possible through improvements in delayed coincidence time resolution. We use our results on Fe57/Ni, and Mössbauer results on the same system, to illustrate a general comparison between the Mössbauer and the TDPAC techniques. Our conclusion is that, although both methods share certain common aspects such as source preparation, there are important differences in the two methods which give one or the other a distinct advantage in various applications.
