Abstract

The Canadian Penning Trap mass spectrometer has been used to determine the mass excesses of ${}^{64}{Ge}$ and ${}^{64}{Ga}$ as −54344(30) keV and −58832.5(39) keV, respectively. Under typical conditions used for modeling x-ray bursts, ${}^{64}{Ge}$ is confirmed as a waiting-point nuclide and can contribute up to 35.5 s to the timescale of the $rp$ process at a peak x-ray burst temperature of 1.5 GK.
