Measurement of Cu K and Ag, In and Sn L X-ray production cross sections by low-energy positron impact

Cu K and Ag, In and Sn L X-ray production cross sections by positron impact have been determined experimentally in the energy range below 30 keV using an X-ray detector with thin Si(Li) crystals. These values have been compared with theoretical estimates derived using the binary encounter formalism. The values for Cu K and Ag L X-rays have also been compared with the results of theoretical calculations using the plane-wave Born approximation with Coulomb and relativistic corrections.
