K shell fluorescence yields were measured for seven elements, Cs, Ba, La Ce,Pr, Nd and Sm, using a Ge(Li) detector. The targets were excited using 59.5 keV gamma rays from an Am-241 radioactive source of strength 100 mCi. The obtained results were compared with the theoretical values and other measured values. The present results are in good agreement with earlier experimental and theoretical results.
