Outline of Final Research Achievements

We study nuclear experiments using gamma-ray pulses provided from high field plasma generated by high peak power laser.　These gamma-ray pulses have excellent features of extremely short pulse, highly intense and continuous energy distribution. These features are suitable for the study of explosive nucleosyntheses in novae and supernovae. We discuss how to generate the suitable gamma-ray pulses using high power laser and experimental methods to simulate nuclear reactions in stellar environments.
