Popis: First two runs with 138.7 g of 100 Mo were done 9202 h and 238 h). Limits on half-lives for 0ν- and 0νχ 0 -decays of 100 Mo were obtained, > 2.3 · 10 21 y and 0.8 · 10 20 y, respectively at 90% CL. Also the limit on the content of radioactive 42 Ar in the natural Ar was obtained, −21 g/g. Perspectives for the future are discussed.
