Title: Experimental challenge to nuclear physics problems in the {nu}p-process

Abstract

Astrophysical stellar reactions at extremely high temperatures involve a variety of problems both in nuclear reactions and nuclear structures. Specifically, the problems in the {nu}pprocess were discussed in this talk based on our recent experimental results with low-energy RI beams and a simulation study. The {nu}p-process is one of the key processes for investigating the mechanism of type II supernovae, and the process could be possibly responsible for 'the excess production' of p-nuclei around mass 90-100. Alpha cluster resonances have been discovered experimentally to play a crucial role for the stellar ({alpha}, p) reactions just above the alpha threshold. Neutron induced reactions in the proton-rich nuclear regions in the {nu}p-process are also suggested to play an important role, which involve nuclear structures of high level density at high excitation energies, probably giant resonances. The discussion also covered the p-nuclei production through the {nu}p-process at around mass 100.
