Outline of Final Research Achievements

This proposal aims to establish the in situ single crystal neutron structure analysis technique of crystalline-state photo-induced phenomena In order to achieve the purpose, a new closed-cycle cryostat with a light guide and 2-axes goniometer for a single crystal diffractometer SENJU at J-PARC was developed and in situ light exposure neutron diffraction measurement of 2-(2’-hydroxyphenyl)benzimidazol (HPBI), in which a photo-induced intramolecular proton transfer is reported, with a Xe light and 425 nm long-cut filter at 18 K was successfully carried out.
