Abstract
The accurate determination of atomic final states following nuclear decay plays an important role in several experiments. In particular, the charge state distributions of ions following nuclear decay are important for determinations of the angular correlation with improved precision. Beyond the hydrogenic cases, the decay of neutral presents the simplest case. Our measurement aims at providing benchmarks to test theoretical calculations. The kinematics of ions produced following the decay of within an electric field were measured using atoms in the metastable and states confined by a magneto-optical trap. The electron shakeoff probabilities were deduced, including their dependence on ion energy. We find significant discrepancies on the fractions of Li ions in the different charge states with respect to a recent calculation.
