“…This indicates that, for the chosen astrophysical conditions, even higher mass accuracies on the order of 1 keV would be needed to fully eliminate mass-induced model uncertainties in this particular case. Such precision levels have recently been demonstrated with an MR-TOF mass spectrometer [119], encouraging a future re-measurement of the 61 Ga mass. However, other nuclear uncertainties in this region are now of higher astrophysical relevance.…”

We report precision mass measurements of neutron-deficient gallium isotopes approaching the proton drip line. The measurements of 60−63 Ga performed with TITAN's multiple-reflection time-offlight mass spectrometer provide a more than threefold improvement over the current literature mass uncertainty of 61 Ga and mark the first direct mass measurement of 60 Ga. The improved precision of the 61 Ga mass has important implications for the astrophysical rp-process, as it constrains essential reaction Q-values near the 60 Zn waiting point. Based on calculations with a one-zone model, we demonstrate the impact of the improved mass data on prediction uncertainties of X-ray burst models. The first-time measurement of the 60 Ga ground-state mass establishes the proton-bound nature of this nuclide; thus, constraining the location of the proton drip line along this isotopic chain. Including the measured mass of 60 Ga enables us to extend the evaluated T = 1 isobaric multiplet mass equation up to A = 60.

“…According to the recent works from other research groups discussing particularly high resolving powers (see e.g. [65,66]), and to the present knowledge of the authors, this is a new record for MRTOF mass spectrometry considering the long measurement time and high number statistics of ions in the spectra. This new achievement will facilitate mass measurements of nuclear isomeric states in future, where R m ≈ 10 6 enables the identification of nuclear isomers (at FWHM level) with excitation energies of, for example, 38 keV for A/q ≈ 40, 93 keV for A/q ≈ 100, and 186 keV for A/q ≈ 200.…”
