Neutirno process with primitive meteorites and high power laser

A huge number of neutrinos emitted in core-collapse supernova explosions (neutrino process) play an important role in stellarnucleosynthesis of some rare nuclides. The study of the neutrino process can contribute to estimation of neutrino energy spectraand explosion mechanism. In the mass region heavier than iron, only three nuclides are known as the neutrino isotopes. If we canfind other candidates for neutrino production, it helps to constrain precisely the neutrino energy spectra emitted from proto-neutronstars. A key input for the calculation of the neutrino process is destruction rates by photodisintegration reactions on excited nucleiat high temperature environments. We have proposed direct measurements of photon-induced reaction cross sections on nucleiexcited by high power laser to simulate stellar environments
