Description
A new type X-ray source has been obtained by proton excitation of elementary targets or compound targets. Using this X-ray source and Si(Li) detector systems mass attenuation coefficients have been determined for copper in the energy range 3.3 - 29.1 KeV, for iron in 3.3-20 KeV. The experimental uncertainties of attenuation coefficients have been reduced to ±1% for intenser isolated characteristic X-rays. The total photoelectric cross sections have been obtained by subtracting scattering cross sections from the measured total cross sections. Comparison of the present experimental results with the past values, as well as between the experimental values and the theoretical calculations, have been presented and discussed.
