Outline of Final Research Achievements

To investigate a primary process of ionizing radiation induced chemical reaction, novel measurement technique of pulse radiolysis, “spatially time-resolved single-shot pulse radiolysis” was proposed and developed. This new technique achieved based on conversion of the information of irradiated location in the sample to the information of transient absorption at the corresponding time by introducing ultra-short electron beam and probe light pulse from fs-laser. The spatially time-resolved single-shot pulse radiolysis technique enables us to obtain 100 ps time window by one-shot measurement and expected to accelerate investigation of dynamics of a primary reaction of radiation chemistry.
