To determine the K alpha and K beta excitation factors, the experimental values of K shell X-ray production cross sections and total absorption photoelectric cross sections were used. The measurements were performed using a Si(Li) detector coupled with 2048 multichannel analyzer and an Am-241 annular radioisotope source which is emitted 59.54 keV gamma-photons. It is observed that the Ka excitation factors are 5-6 times larger than the K beta excitation factors. The measured excitation factors were compared only with theoretical calculated ones since there are no other experimental reports for the present elements in the literature. The present experimental values of K alpha and K beta excitation factors are in satisfactory agreement with the theoretical results. (C) 2015 Published by Elsevier Ltd.
