We propose a -decay experiment based on a sample of ultracold
atomic tritium. These initial conditions enable detection of the helium ion in
coincidence with the . We construct a two-dimensional fit incorporating both
the shape of the -spectrum and the direct reconstruction of the neutrino mass
peak. We present simulation results of the feasible limits on the neutrino mass
achievable in this new type of tritium -decay experiment.
