Conversion electron yield X-ray absorption fine structure measurements under atmospheric conditions

The detection of a sample current under atmospheric conditions was applied to XAFS measurements of a Ni foil and NiO powders, and the feasibility of the conversion electron yield (CEY) detection was examined. The obtained XAFS spectra were compared with those obtained using the conventional transmission method; it is concluded that fairly good statistics can be obtained using the CEY method and that the obtained spectra show an identical structure to those obtained using the transmission method.
