Coherent and Compton scattering cross sections for the elements Mg, AI, Mn, Ni, Cu, Y, Mo, Pd, Ag, Cd, In, Sn, Sb, Au and Pb have been measured at 32.06 keV (Ba K~t) and 33.29 keV (La Ka) x-ray energies. Measurements have been performed using an x-ray tube with a secondary excitor system as the excitation source instead of radioisotopes. In order to improve the efficiency of the detection system the excitation source detector and the sample assembly were placed in a vacuum chamber and a pressure of 10 -2 mbar was maintained throughout the measurements. The present system reduced the scattering and background effects considerably and improved the monochromaticity. Experimental coherent scattering cross sections are compared with the noimalised integrated coherent scattering cross sections. Experimental results are higher around the edges indicating the oscillatory nature of coherent intensity, resonance behaviour and fine structure effects. Experimental incoherent scattering cross sections are higher than the theoretical estimates for low medium Z elements and lower for heavy elements. The latter is due to the effect of electron binding at low photon energies for heavy elements.
