CONVERSION ELECTRON MOESSBAUER SPECTROSCOPY

摘要

CEMS has been widely used in various fields, based on development of detection techniques of electrons. Especially ICEMS and XMS using a He gas counter have been used for characterization of surface products of chemically treated steel and industrial materials. It is further expected that GACEMS, DCEMS and AEMS would be more often used for layer by layer analysis of the thinner solid surface. ICEMS, DCEMS and XMS would become more powerful by simultaneous measurement at lower temperatures, and further by combining with another analytical methods such as EPMA, XRD and X-ray fluorescent analyzer. A simple counter can be easily improved according to the purpose of a study. In situ CEMS and DCEMS could afford us more detailed and useful information on the chemical structure and orientation of intermediate products in the surface layers of materials exposed in various environments.
