Abstract

Any conventional soft x-ray appearance potential spectrometer may be converted to an isochromat spectrometer by placing an absorber foil of suitably chosen thickness in front of the x-ray detector. In the present work, we demonstrate the principle and work out in detail the properties of an aluminum absorption foil. Isochromats of a hafnium sample are compared to results obtained with a crystal x-ray spectrometer. Also, the equivalence of an isochromat and an SXAPS measurement at the same energy will be shown. The densities of unoccupied states as derived from the respective experiments are in pretty good agreement.
