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

摘要

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.
