| 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.
