Trapped ions are the ideal source for high precision decay studies. The decaying nuclei are confined practically free in space and the decay products don't experience energy loss or a change in direction due to scattering. An example for high precision decay studies that may eventually be carried out at LEBIT either in ion or atom traps are electron-neutrino correlation studies.
In the beta-decay of a nucleus a beta-particle and a neutrino are emitted. The observation of the correlation between the direction of emission of the beta-particle and the neutrino is one possibility to test if our Standard model of Particle Interaction is not complete. The model in its present form predicts for specific decays types a well-defined correlation between the emission of neutrino and beta-particle. If deviations are found then the present (V-A) structure of the charged weak interaction is not sufficient and extensions are required. An experimental difficulty is that the neutrinos are practically undetectable. Therefore, the correlation of the direction of the recoiling nucleus and the beta-particle is measured from which the beta-neutrino correlation can be calculated.
Such experiments can be carried out both in atom and ion traps.
