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 96Ag, 98Ag, 96Cd and 98Cd. We report on recent measurements of β-delayed proton branching ratios for 96Ag, 98Ag, and 98Cd at the on-line mass separator at GSI.
