Abstract
The scattering half-thickness for electrons has been experimentally determined to be ≈ 0.25 μg/ (≈ 13 Å carbon) for 1169-eV electrons and ≈ 0.21 μg/ (≈ 10 Å carbon) for 920-eV electrons. The corresponding mass-scattering coefficients are 2.75 ± 0.19 and 3.32±0.37 /μg. Other useful and related attenuation parameters are defined and calculated. These results were obtained from measurements of the attenuation by thin carbon films (5-60 Å) of monoenergetic photoelectrons originating from gold substrates irradiated with Mg x rays, and also from measurements of the concomitant increase in carbon photoelectron intensity. Scattering of electrons in the energy range about 1 keV is greater than has generally been indicated.
