Oral Presentation

Gamma rays, X-rays and UV radiation arising from solar activity and supernova explosions in our galaxy cause changes in the chemical composition of the stratosphere from ~10 - 50 km altitude. The effect of radiation on the stratosphere is then recorded in the chemical composition of terrestrial ice. The effect observed in the ice cores which we have obtained from the Dome Fuji research station...

100. Neutrino process with primitive meteorites and high power laser

Oral Presentation

A huge number of neutrinos emitted in core-collapse supernova explosions (neutrino process) play an important role in stellar nucleosyntheses of rare some nuclides such as Li-7, Be-11, F-19, Nb-92, La-138, and Ta-180. The study of the neutrino process can contributes to estimation of neutrino energy spectra and explosion mechanism. In the mass region heavier than iron, only three nuclides are...

103. Indirect studies on astrophysical reactions at the low-energy RI beam separator CRIB

Hidetoshi Yamaguchi

Oral Presentation

CRIB (CNS Radioisotope Beam Separator) is a low-energy RI beam separator operated by CNS, University of Tokyo, located at RIBF of RIKEN Nishina Center. Various experimental projects based on interests for nuclear astrophysics have been carried out at CRIB, forming international collaborations. We present recent activities on nuclear astrophysics at CRIB. We have studied proton/alpha...
