Experimental M X-ray fluorescence cross sections for the elements Pt, Au and Pb have been measured at incident photon energies 6.47 and 7.57 keV. Theoretical M X-ray fluorescence cross sections for the elements Yb, W, Hg, Tl, Bi and Ra at 6.47 and 7.57 keV are also calculated. Experimental results are compared with the theoretical values based on relativistic Dirac-Hartree-Slater calculations of Chen et al. and non-relativistic calculations of McGuire. The average M shell fluorescence yields have been deduced using experimental cross section values and the theoretical M shell photoionization cross sections. Results are compared with the available theoretical values.

Abstract
Experimental M X-ray fluorescence cross sections for the elements Pt, Au and Pb have been measured at incident photon energies 6.47 and 7.57 keV. Theoretical M X-ray fluorescence cross sections for the elements Yb, W, Hg, Tl, Bi and Ra at 6.47 and 7.57 keV are also calculated. Experimental results are compared with the theoretical values based on relativistic Dirac-Hartree-Slater calculations of Chen et al. and non-relativistic calculations of McGuire. The average M shell fluorescence yields have been deduced using experimental cross section values and the theoretical M shell photoionization cross sections. Results are compared with the available theoretical values.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
