We have developed a compact experimental set-up for X-ray absorption fine structure (XAFS) measurements in He at atmospheric pressure (AP) in the soft X-ray region and used it for Mg and Cl K-edge XAFS measurements of MgCl{sub 2} and MgCl{sub 2{center_dot}}6H{sub 2}O. The spectra of MgCl{sub 2{center_dot}}6H{sub 2}O measured in He at AP were significantly different from those measured in vacuum. This suggests the importance of performing soft X-ray XAFS experiments under AP to obtain reliable spectra from hydrated compounds.
