Abstract
First two runs with 138.7 g of Mo-100 were done (202 h and 238 h). Lim its on half-lives for O nu- and O nu chi(0)-decays of Mo-100 were obta ined, > 2.3 . 10(21) y and 0.8 10(20) y, respectively at 90% CL. Also the limit on the content of radioactive Ar-42 in the natural Ar was ob tained, < 5 . 10(-21) g/g. Perspectives for the future are discussed.
