摘要：

K-shell X-ray fluorescence cross-sections for the elements Mn, Fe, Ni, Cu, Zn, Ge, As, Br, Rb, Sr, Zr, Nb, Pd and Ag have been measured at the excitation energy of the 59.54 keV gamma -rays from an Am-241 radioactive source of strength 100 mCi. In addition, measurement of K X-ray fluorescence yields for these elements at the same excitation energy have also been carried out. The experimental results are compared with the literature experimental values, theoretical predictions, and semiempirical fits. (C) 2001 Elsevier Science Ltd. All rights reserved.
