Outline of Final Research Achievements

Efficient cooling of molecules from room temperature and long-time observation of their properties are necessary to understand the characteristic molecular dynamics in the ultracold temperature. We proposed the new method to explore the low-temperature molecular dynamics by extending the experimental technique of superfluid helium droplets, that are at present the most ideal cold matrix medium. In this research period, we generated an intense, pulsed droplet beam consisting of micron-size helium droplets. These droplets have a enough capability of capturing small-size molecules to large, nano-clusters.
