Özet

In this paper, we report on measurements of K shell, L shell-subshell and M shell-subshell photoeffect cross-sections for 21 high-atomic-number elements between Tb (Z = 65) and U (Z = 92) at 123.6 keV. These photoeffect cross-sections have been measured by using our earlier measurements of the K-shell X-ray production cross-sections. The measured photoeffect cross-sections have been compared with calculated theoretical values. It is clear that the results compare well with theoretical values within an experimental average error. At 123.6 keV, these cross-sections have been measured for the first time. The results have been plotted versus atomic number. (c) 2007 Elsevier Ltd. All rights reserved.
