...and momentum, of course.

The kinetic energies and momenta of the beta-decay electron (or positron) and remaining (recoiling) nucleus are slightly different for different neutrino masses. For that matter, so is the kinetic energy and momentum of the outgoing neutrino.

Therefore, for three different neutrino masses, the entire final state of the decay (neutrino, electron and nucleus) is a superposition of three states with (very) slightly differing neutrino mass, and with (very) slightly differing kinetic energies and momenta for the electron and nucleus.
For measuring the mass of neutrinos, check out for Kurie Plot.
