Abstrae~A new, simple and direct method proposed earlier by us has been employed here to measure the total photoelectric cross sections of rare earth elements in the range 58 ~< Z ~< 66 present in compounds at 12Y6 keV and 145.4 keV photon energies. The K X-ray fluorescence intensities emitted by th

In this paper we report on measurements of Ka 1 , Ka 2 , Kb 0 1 and Kb 0 2 X-ray production cross sections and K shell fluorescence yields for 21 high atomic number elements. The targets were irradiated with c-photons at 123.6 keV from 57 Co annular source. The K X-rays from different targets were d
