11.08.2015 | High precision measurement of decay energy of Holmium-163 paves way to the neutrino mass

With the Shiptrap experiment at GSI an international team of scientists succeded in measuring the decay energy of Holmium-163 directly and with high precision. Its decay energy is of exceptional interest because it paves the way for the determination of the mass of the neutrinos which are emitted in the decay of Holmium. The experimental determination of the neutrino mass is one of the great unsolved questions in physics.
