First results of a search for double beta decay of {sup 100}Mo with the NEMO 2 detector
Double beta decay of {sup 100}Mo (172g) is studied with the NEMO 2 detector in the Frejus Underground Laboratory. The experiment has now accumulated 2485 hours of data taking. A clear signal of 380 events for 2{beta}2{nu} decay has been obtained corresponding to a half-life of T{sub {1/2}} = 1.0 {plus_minus} 0.08 (syst.) 10{sup 19} y. Limits are presented for 2{beta}(0{nu}, {chi}), 2{beta}0{nu} (ground state and excited states 2{sub 1}{sup +} and 0{sub 1}{sup +}). The experiment will run til October 1993.
