Using the neutrino oscillations and neutrinoles double beta decay experimental data we reconstructed an upper limit for the three generation neutrino mass matrix. We compared this matrix with the predictions of the minimal supersymmetric (SUSY) model with R-parity violation (Rp / ) and extracted stringent limits on trilinear Rp / coupling constants λi33, λ′i33. Introducing an additional U(1)X flavor symmetry which had been successful in explaining the mass hierarchy of quarks and charged leptons we were able to relate various Rp / parameters. In this model we found a unique scenario for the neutrino masses and the Rp / couplings compatible with the neutrino oscillation data. Then we derived predictions for certain experimentally interesting observables.
