The aim of this study was to determine of K shell fluorescence yields (omega(K)) of Hf compounds. The targets were irradiated with gamma-photons at 123.6 keV from Co-57 annular source. The K X-rays from different targets were dedected using a (Ultra-LEGe) semiconductor dedector with a resolution of 150 eV at 5.9 keV. The measured K shell fluorescence yields results compare with the literature semi-emprical prediction that taken from Krause [1].
