Abstract

The lecture includes two parts: One is a discussion on the technology for developing RIB beam facility based on the in-flight method and relevant experimental technology. The second part is a discussion on experimental efforts for studying the breakout process from the pp-chain region based on recent works with low energy RI beams. The discussion of the second part specifically covers the problem of the vp-process in type II supernovae in terms of alpha cluster nature for the reactions. [ABSTRACT FROM AUTHOR]

Abstract

Several reactions have been experimentally studied, including the 12N(d,n)13O and the ones induced by the 3He+12C entrance channel. The former was carried out at the CRIB facility of University of Tokyo, aiming to indirectly determine the astrophysical reaction rates of the 12N(p,γ)13O reaction. For the 3He+12C entrance channel, many excited states of several nuclei are populated and the angular distribution of each state is being analyzed. [ABSTRACT FROM AUTHOR]

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 νpprocess were discussed in this talk based on our recent experimental results with low-energy RI beams and a simulation study. The νp-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 (α, p) reactions just above the alpha threshold. Neutron induced reactions in the proton-rich nuclear regions in the νp-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 νp-process at around mass 100. [ABSTRACT FROM AUTHOR]

Abstract

The first direct measurement of the 11C(α, p)14N reaction cross section of astrophysical interest has been performed for the center-of-mass energies from 1 to 4.5 MeV with the CRIB (Center for Nuclear Study Radioactive Ion Beam separator). We successfully distinguished the transition to the ground state of 14N and that to the second excited state with a comparable yield. The resonant shapes in the preliminary excitation function for the ground state transition have been confirmed to be consistent with the ones from the time-reversal reaction data of previous experiments.
