Densities of Unfilled One-Electron Levels in the Elements Vanadium and Iron through Zinc by Means of X-Ray Continuum Isochromats

Abstract
X-ray continuum isochromats have been obtained at a photon energy of 530 eV from bulk samples of vanadium, iron, cobalt, nickel, copper, and zinc under ultrahigh-vaccum conditions. The isochromats have been partially corrected for the smearing due to the spectral window of the two-crystal potassium acid phthalate (KAP) monochromator used and for the distortion due to the nonsingular nature of the electron spectra in the samples. The corrected data may be interpreted as measures of the densities of available one-electron states in these materials.
