Differential and total M-shell X-ray production cross-sections of some selected elements between Au and U at 5.96 keV

Differential M-shell X-ray production (MXRP) cross-sections for selected heavy elements between An and U have been measured at 5.59 keV incident photon energy, respectively at seven angles varying from 120 degrees to 150 degrees a Si(Li) detector. The differential M-shell X-ray production cross-sections have been derived, using M-shell fluorescence yields, experimental total M X-ray production cross-sections and theoretical M-shell photoionization cross-sections. The differential M-shell X-ray production cross-sections have been compared with the semi-empirical fits. The measured differential M X-ray production cross-sections have been found within experimental error. Differential M X-ray production cross-section can be fitted to the Sigma(n)a(n)Z(n) (n = 2) as a function of cos theta. Total M X-ray production cross-sections have been derived using the fitted values.(c) 2007 Elsevier B.V. All rights reserved.
