The rp-process and new measurements of β-delayed proton decay of light Ag and Cd isotopes

Abstract Recent network calculations suggest that a high temperature rp-process could explain the abundances of light Mo and Ru isotopes, which have long challenged models of p-process nuclide production. Important ingredients to network calculations involving unstable nuclei near and at the proton drip line are β-halflives and decay modes, i.e., whether or not β-delayed proton decay takes place. Of particular importance to these network calculation are the proton-rich isotopes 96 Ag, 98 Ag, 96 Cd and 98 Cd. We report on recent measurements of β-delayed proton branching ratios for 96 Ag, 98 Ag, and 98 Cd at the on-line mass separator at GSI.
