Extended x-ray bremsstrahlung isochromat of Pd

Abstract

The x-ray bremsstrahlung isochromat of Pd has been measured up to 130 eV above the Fermi level for a photon energy of 5415 eV with a resolution of 1.8 eV. The fine structure of the Pd isochromat is interpreted as due to the density of p-type states according to the momentum-specific energy dependence of the transition probability. Fourier analysis was performed and an interatomic distance of 2.76 A\r{} was obtained for Pd. The authors propose a simple formula for calculations of x-ray bremsstrahlung isochromats by using a factorization of an x-ray bremsstrahlung isochromat into atomiclike and solid-state contributions.
