| الوصف: | Mass excesses of short-lived $A=2Z\ensuremath{-}1$ nuclei $^{63}\mathrm{Ge}$, $^{65}\mathrm{As}$, $^{67}\mathrm{Se}$, and $^{71}\mathrm{Kr}$ have been directly measured to be $\ensuremath{-}46\text{ }921(37)$, $\ensuremath{-}46\text{ }937(85)$, $\ensuremath{-}46\text{ }580(67)$, and $\ensuremath{-}46\text{ }320(141)\text{ }\text{ }\mathrm{keV}$, respectively. The deduced proton separation energy of $\ensuremath{-}90(85)\text{ }\text{ }\mathrm{keV}$ for $^{65}\mathrm{As}$ shows that this nucleus is only slightly proton unbound. X-ray burst model calculations with the new mass excess of $^{65}\mathrm{As}$ suggest that the majority of the reaction flow passes through $^{64}\mathrm{Ge}$ via proton capture, indicating that $^{64}\mathrm{Ge}$ is not a significant $rp$-process waiting point. |
