X-ray absorption spectroscopy on solid krypton np to 20 GPa
Résumé
High-pressure properties of krypton were investigated by energy-dispersive extended x-ray absorption fine-structure spectroscopy in a diamond anvil cell at room temperature. The equation of state agrees very well with x-ray diffraction data. The pressure dependence of the Debye-Wailer factor was determined and compared with calculations using pair potentials. The analysis of the xray absorption near-edge structure part of the spectrum shows the possibility of measuring the pressure in bubbles of krypton implanted in metallic matrices.
