The detailed chemical abundance patterns of barium stars HD204075 and HD101013 are used for investigations of heaviest s-process elements. Special attention is devoted to elements with Z>70, up to Pb. Spectrum synthesis method is used for abundance calculations. High resolution spectra were obtained at 2.7 meter telescope of McDonald observatory (spectral resolution R=60,000, signal to noise ratio S/N>400) and VLT (R=80,000, S/N>400). CNO and Fe abundances are found for HD204075 and HD101013. Heavy (Z≥64) elements abundances are found for HD204075. The results of previous investigations of HD204075 and our data is in good aggrement with s-process enriched pattern. Our estimates show that the abundances of Z≥64 elements in HD101013 are significantly higher than in HD204075.
