The first search of double beta decay in 144Sm and 154Sm have been performed. New limits on half-life relatively to the two-neutrino modes of double beta decays were set. 3. Measurements were performed with zinc tungstate crystal scintillators grown by low-thermal-gradient Czochralski technique in different growth conditions. Influence of different crystallization conditions on radioactive contaminations of the crystals was studied. Techniques of measurement of ultra-low radioactive contaminations were developed, which is important in utilizing of this crystals in purposes of double beta decay searches in zinc and tungten nuclides.
