In the ββ decay, there are in general three parameters: the neutrino mass (mν) and two right-handed weak current parameters (λ and η). It is shown how to distinguish their contributions experimentally. Two useful measurable quantities are single electron kinetic energy spectrum and the angular correlation between two emitted electrons. The numerical results are given for the 76Ge case.
