A double cell for X-ray absorption spectrometry of atomic Zn

[摘要] A high-temperature cell with a double wall design has been constructed for X-ray absorption spectrometry of metal vapors. The inner cell, assembled from a corundum tube and thin plates without welding or reshaping, serves as a container of the vapor sample. It is not vacuum tight: instead, the outer tube provides inert atmosphere. Several spectra of K-edge atomic absorption of Zn were obtained in the stationary working regime blow the Zn boiling point. The Kedge profile shows an extremely strong resonance and, above the continuum threshold, coexcitations of the outer electrons. (C) 2002 Elsevier Science B.V. All rights reserved.
