Photon-attenuation cross sections for beryllium from 1. 5 to 8. 0 keV

Journal Article · · Phys. Rev. A; (United States)
The photon-attenuation cross sections for beryllium have been measured with use of a Si(Li) detector spectrometer in the energy range 1.5--8.0 keV. The K..cap alpha.. and L..cap alpha.. x-ray lines produced by the heavy-ion interaction with the thick targets of different materials have been used as the low-energy photon sources. High-purity (99.8%) beryllium foils are used. The experimental errors are less than 2.5%, except when stacked foils were used for the Cu K..cap alpha.. line, in which case the error was 2.9%. The results are compared with the available measured values in this energy region and also with widely used tabulated values of Storm and Israel, of Veigele, and with recent tabulations of Hubbell. Furthermore, the photoeffect cross sections are derived from the total attenuation cross sections by subtracting the scattering cross sections and are compared with Scofield's theoretical calculations.
