Investigation of double beta decay with the NEMO-3 detector
Abstract
The double beta decay experiment NEMO~3 has been taking data since February 2003. The aim of this experiment is to search for neutrinoless () decay and investigate two neutrino double beta decay in seven different isotopically enriched samples (Mo, Se, Ca, Zr, Cd, Te and Nd). After analysis of the data corresponding to 3.75 y, no evidence for decay in the Mo and Se samples was found. The half-life limits at the 90% C.L. are y and y, respectively. Additionally for decay the following limits at the 90% C.L. were obtained, y for Ca, y for Zr and y for Nd. The decay half-life values were precisely measured for all investigated isotopes.
