Abstract

The feasibility of RIKEN high-resolution PIXE system for direct chemical state analysis of 3d transition elements was examined. K β spectra of Cr and Fe from several compounds were measured in air at atmospheric pressure using a crystal spectrometer consisting of a position-sensitive proportional counter and a curved crystal in v. Hamos geometry. Fine structures which reflect the chemical states of Cr and Fe were well recognized with the measuring time of tens minutes.
