Abstract
Conversion He+ ion yield (HIY) XAFS measurement, in which He+ ion is collected using the conversion electron yield (CEY) cell under atmospheric He gas environment, has been attempted at Eu K-absorption edge (48.5keV) for europium dioxymonocyanamide. The shape of Eu K-XAFS spectrum measured by the HIY method was similar to that measured by the conventional transmission method, while the signal-to-background ratio decreased with an increase in absorption edge energy, owing to low Auger electron emission probability. The evidences suggest that the HIY method is still applicable to the XAFS measurement for materials which could not be pulverized at such higher energy region.
