Outline of Final Research Achievements

In this research, we implemented an experimental system for realizing an ultracold mixture of atoms and ions. We succeeded in determining the cross sections by measuring atom-ion collisions in a wide collision energy scale ranging from milli kelvin to a few kelvin. We also precisely investigated the elastic collision rate and the inelastic loss rate, and it is confirmed that our atom-ion mixture is useful for realizing atom-ion sympathetic cooling and atom-ion interaction in a quantum regime. These results can be an essential step for atom-ion sympathetic cooling and also for exploring the dynamics of chemical reactions in ultracold temperature, which governs the chemistry in an interstellar space.
