In general supersymmetric theories with ultralight superpartners of neutrinos and in specific supersymmetric models with spontaneous violation ofR-parity, neutrinoless double beta decay can occur with the emission of two majorons. We discuss the differential electron energy spectrum in this case and possible constraints on the masses of superlattices that arise from the available data on double beta decay.
