Outline of Final Research Achievements

In order to reveal the physical properties of actinoid liquids, we evaluated the physical properties (especially viscosity) of molten materials by levitation techniques, conventional method with container, and molecular dynamics simulation. By using appropriate levitation techniques, we showed that both oxides and metals can be measured. There is a large mismatch in the measured viscosity between levitation and conventional methods, which suggests that levitation is necessary for the measurement of the physical properties of actinoid liquids since it has high reactivity and high melting point. As for the molecular dynamic simulation, we found an potential function that can reproduce the measured viscosity.
