| Outline of Final Research Achievements |
The development of organic scintillator crystals for neutron detection was performed. The crystal growth of the organic crystals which showed fast scintillation decays under 10 ns and high light yield was succeeded. The organic crystals were irradiated by neutron flux and their response characteristics were evaluated for neutron detection applications. We focused on crystal structure of π-electron number density and bonding positions, and organic crystals, such as carbazole and anthracene compounds, were grown systematically. The relationships between their crystal structure and their luminescent properties were suggested.
