Özet

L-3 X-ray production cross sections have been measured for the elements in the atomic range 57 less than or equal to Z less than or equal to 68 at 59.5 keV. The values of L-3 subshell fluorescence yields (omega(3)) have been measured for the same elements using the presently measured cross section values and the theoretical L-i subshell photoionisation cross sections, Coster-Kronig transition probabilities, emission rates and vacancy transfer probabilities. The measured X-ray production cross section values are in general agreement with the theoretical values evaluated using L-3 subshell fluorescence yields. Coster-Kronig transition probabilities, emission rates, vacancy transfer probabilities and subshell photoionisation cross sections. Furthermore, the values of L-3 subshell fluorescence yields are in good agreement with the theoretical values. (C) 2002 Elsevier Science Ltd. All rights reserved.
