| Outline of Final Research Achievements |
Early process of radiation chemistry of various alkanes was studied by pulse radiolysis method for elucidate the radiation induced bond cleavage of saturated hydrocarbon polymers. Diffusion limited formation and ultra-fast formation of biphenyl radical anions were observed in not only dodecane, but also octane and hexane. This suggests that ultrafast electron transport generally occurs in the early process of alkane radiation chemistry. As a result of measuring the polymer resist in a THF solution, the initial yield of solvated electron was decreased. Moreover, thin film pulse radiolysis was developed for application to polymer materials. In the case of water film, it was possible to measure up to 71 μm thick with RF electron gun accelerator and 7 μm thick with large charge L band accelerator.
