Abstract

An experiment to measure the bound β-decay of the neutron into a hydrogen atom and an electron anti-neutrino is described. Observation of such a decay would open an alternative pathway to physics beyond the Standard Model, in particular right-handed current admixtures in the weak interaction as well as the handedness of the neutrino. The experiment is planned at the through-going beam tube SR6 at the FRM2 high-flux reactor in Garching. Although the branching ratio of this decay is expected to be only 4·10 ^-6 of the normal neutron β-decay [1], a sufficient decay rate due to the high flux of neutrons available for the experiment is expected. Simulations have shown that the measurement is feasible, with proper shielding being the critical factor. The experimental setup is currently being studied, testing different detection techniques for H(2s) at the TUM.
