✦ Synopsis

First two runs with 138.7 g of "'MO were done (202 h and 238 h). Limits on half-lives for Ou-and Ovx"-decays of "'MO were obtained, > 2.3. 1021 y and 0.8. 102' y, respectively at 90% CL. Also the limit on the content of radioactive 42Ar in the natural Ar was obtained, < 5. 10S21 g/g. Perspectives for the future are discussed.
