Abstract

The full data set of the NEMO-3 experiment has been used to measure the half-life of the two-neutrino double beta decay of \[^{100}\]Mo to the ground state of \[^{100}\]Ru, \[T_{1/2} = \left[ 6.81 \pm 0.01\,\left( \text{ stat }\right) ^{+0.38}_{-0.40}\,\left( \text{ syst }\right) \right] \times 10^{18}\] year. The two-electron energy sum, single electron energy spectra and distribution of the angle between the electrons are presented with an unprecedented statistics of \[5\times 10^5\] events and a signal-to-background ratio of \[\sim \] 80. Clear evidence for the Single State Dominance model is found for this nuclear transition. Limits on Majoron emitting neutrinoless double beta decay modes with spectral indices of \[\mathrm{n}=2,3,7\], as well as constraints on Lorentz invariance violation and on the bosonic neutrino contribution to the two-neutrino double beta decay mode are obtained.
