Total photoionization cross-sections of Ar and Xe in the energy range of 2.1-6.0Â keV

Total photoionization cross-sections of Ar and Xe have been accurately measured in the photon energy region of 2.1-6.0 keV, using a four-electrode ion chamber with monochromatized synchrotron radiation. Experimental data are presented in both graphical and tabular forms and compared with previous data reported in the literatures.
