  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
$\beta$-halflives and decay modes, i.e., whether or not $\beta$-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 $\beta$-delayed proton branching ratios for
$^{96}$Ag, $^{98}$Ag, and $^{98}$Cd at the on-line mass separator at GSI.
