متن کاملDensity Measurement for Expanded Fluid Selenium up to the Liquid-Vapor Supercritical Region by the X-ray Absorption Method
Density of expanded fluid selenium was measured in the temperature and pressure ranges up to 1650 •Ž and 700 bar including the liquid-vapor critical point by the x-ray absorption method . For the measurements, a new type of cell made of polycrystalline sapphire and a high-pressure vessel of authors' own design were developed We obtained the critical temperature, pressure and density of 1615•}5 ...
متن کاملPhoton interference x-ray absorption fine structure
We report about a fine structure in x-ray absorption spectra, named photon interference x-ray absorption fine structure (pXAFS). pXAFS is due to the interference of x-rays inside the sample and extends across absorption edges. Using a platinum foil pXAFS was measured in a high precision absorption experiment. Excellent agreement with a theoretical pXAFS simulation is achieved in the energy rang...

متن کاملX-ray Absorption Fine Structure of Free Selenium Clusters
Although clusters have attracted great interest as intermediate states between atomic and condensed states of matter [1], general methods for the size-selective structural analysis of neutral clusters have not been established so far. Recently we measured the Pho toe lec t ron Pho to ion Coincidence (PEPICO) spectra for selenium dimer Se2 and larger species such as Se5 [2,3]. The PEPICO spectra...
