Measurement of proton capture cross sections relevant to rp process with Coulomb dissociation
Abstract
We have studied proton capture reactions on unstable proton-rich nuclei relevant to rapid proton-capture (rp) process using a Coulomb dissociation method. Using this method, three stellar reactions, 22Mg(p, γ)23Al, 26Si(p, γ)27P, and 30S(p, γ)31Cl were studied at RIKEN Nishina Center. The radiative widths of the first excited state in 23Al and 27P, which are relevant to the stellar reactions, were obtained. We discuss the details of the Coulomb dissociation the astrophysical implications obtained from our studies.
