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 (T_1/2 > 2.7⋅10²² y) and ⁸²Se (T_1/2 > 1.5⋅10²² y) have been obtained. Corresponding bounds on the Majoron-neutrino coupling constant are <g_ee > < (0.4-1.9) ⋅ 10^-4 and < (0.66-1.7) ⋅ 10^-4.
