Abstract
The NEMO-3 tracking detector is located in the Fréjus Underground Laboratory. It was designed to study double beta decay in a number of different isotopes. Presented here are the experimental half-life limits on the double beta decay process for the isotopes 100Mo and 82Se for different majoron emission modes and limits on the effective neutrino–majoron coupling constants. In particular, new limits on “ordinary” majoron (spectral index 1) decay of 100Mo (T1/2 > 2.7×1022 yr) and 82Se (T1/2 > 1.5×1022 yr) have been obtained. Corresponding bounds on the majoron–neutrino coupling constant are 〈gee〉 <(0.4–1.8)×10−4 and <(0.66–1.9)×10−4.
