HIGH-FIELD MOSSBAUER PHASE-ANALYSIS

Advantages and disadvantages of high-field Mossbauer phase analysis ar e discussed. As examples, two industrial samples were investigated. On e sample is a corroded steel plate, and one is a soil sample. In both cases an identification of the iron-containing phases was required. It is shown that the applied field technique is capable of eliminating s ome of the ambiguities present in zero-field Mossbauer experiments, bu t at an increased cost. The limitations of a simple least-squares mode l are discussed.
